Chemistry Formula For Using the Cell For the Rechargeable Battery

Chemistry Formula For Using the Cell For the Rechargeable BatteryThe chemical potential energy definition is the basis for the development of chemical potential energy conversion to the fuel cells. A step beyond the concept of electricity, it is an alternative source of energy that involves the conversion of chemical potential energy into electricity in microcells. A fuel cell is a specific fuel cell that transforms chemical potential energy into usable electrical energy.Fuel cells are used in various applications such as automobile engines, tools, aircraft, ships, and so on. They are of two types, stationary and portable. The former requires some kind of a fuel or an oxidizing catalyst, whereas the latter can be manufactured in situ in the form of small bricks.A fuel cell consists of the electrodes, which are designed to hold the fuel molecules in liquid form. The other component is the active gas, which comes from the air or the environment. It is used to activate the reaction betw een the electrons and the gases. The purpose of the reaction is to generate electricity through the energy stored in the fuel molecules.In the chemical equation for the cell, there is a single fundamental chemical property that determines the way in which the energy is converted into electricity. This is the chemical potential energy definition. In general, the more negative the potential energy, the greater the chance of negative oxidation and vice versa.The power of the battery is directly proportional to the power capacity of the battery and the power density of the battery. A common theory on this aspect is that the power of the battery increases with the square of the discharge rate. Power is measured in watts per kilogram, and power density is measured in kilowatts per square meter. Power density is a useful measurement for the fact that this quantity indicates the power output of the battery.Arechargeable battery is comprised of two kinds of materials. These are the metallic as well as the non-metallic materials. Non-metallic materials are the ones that are normally used in conventional car batteries.What we have learned from the original chemical potential energy definition is that the most important characteristic of the battery is the chemical potential energy it generates. From this, we can conclude that the formula for determining the power of the battery is given by the formula P=I*G (where P is the power of the battery, I is the voltage of the battery, G is the power density of the battery and I am the power of the battery multiplied by the discharge rate).

The Volume of a Cube Tutors

The Volume of a Cube Tutors A cube is a 3-dimensional geometric figure which has length, width and a height. However the most important property of a cube is that all the sides are equal in measure. This implies that the length, width and the height are equal to each other, due to which it is enough to have only a single side measure. The volume of a cube is the amount of space contained inside the given cube and it can be calculated by the volume of the cube formula. Example 1: What is the volume of the cube whose side measures 10m? Given the side length of the cube, s = 10m Volume of a cube is the amount of space contained inside the cube and it is given by the formula: Volume of a cube, V = s3 Therefore volume of the given cube, V = (10m)3 This gives: Volume, V = 1000m3 Therefore the volume of a cube whose side measures 10m is 1000m3 Example 2: What is the volume of the cube whose side measures 6m? Given the side length of the cube, s = 6m Volume is the amount of space contained inside a cube and it is given by the formula: Volume of a cube, V = s3 Therefore volume of the given cube, V = (6m)3 This gives: Volume, V = 216m3 Therefore the volume of a cube whose side measures 6m is 216m3

The Different Classes Youll Have In College

The Different Classes You'll Have In College Class schedules and formats are pretty routine in high school. You arrive around eight in the morning, situate yourself in an ordinarily-sized classroom for typically no more than 50 minutes, then move on and repeat that process about seven times throughout the day. Once that designated time in mid-afternoon strikes, youre done for the day and free to return home. This high school class routine is comfortable. You know what to expect and when to expect it. Moreover, there arent many surprises when it comes to the type of classes youll encounter. They all last about the same amount of time and require the same kind of attention from you. In college, however, it is not that predictable. College students get the freedom to create their own schedule with the options of many different types of classes that they need to cover before they graduate. But the subject matter isnt the only thing that differs these classes from one another. Many varying elements make up the final product of a college class, leaving it to fall under one of a few categories. It is important to realize what kind of class you are signing up for, past the title and course description. You will be far better prepared for the course if you know how long each session lasts, how frequently it occurs throughout the week, how much discussion versus hands-on work is involved, etc. Thankfully, it is quite easy to recognize which category your course falls under. Go through the following list to determine what your various classes are going to need from you. Some will require more energy, some will require more talking, some will require more research, and some will require much less of these things. It just depends on certain factors and is for you to figure out before you get started. The 3 Days a Week Discussion: This class will hit closest to home for recent high school graduates. Usually 50 minutes long on Monday/Wednesday/Friday, this type of class places you in a typical classroom setting with approximately 20-25 students. You will sit at your desk, take notes, have discussions, and occasionally break into small groups for further in-class assignments. There is nothing too intimidating about this type of class, as it requires the same sort of regular attendance, participation, and classmate interaction that you are used to. You will need to be significantly more invested in it than you were in high school, however, if you want to effectively grasp the material but that, of course, applies to college-level classes in general. This type of class will be most comfortable for you because its approach is fairly simple and recognizable. Here are 5 habits to avoid during classthat you may want to check out. The Giant Lecture: The image of 200 students in endless rows of a lecture hall is one of the most popular visualizations of college academia. It is a classic type of class and one that you will really only learn about by directly experiencing it. Make yourself aware of how different the environment will be beforehand, however. It is a give-in that the room will be large and a bit overwhelming, but you should also recognize how different the seating will be from the common desk you are used to. Especially if the lecture has the maximum amount of students registered, you will be placed extremely close to your peers and have very little room to take notes. It is possible and necessary to do, but a little challenging at first with the lack of much personal space. Be ready to miss some of the things the professor says, as he or she will be at a distance from you and speaking to an exceptionally large group of people. You will need to catch up on your own time, which is one of the biggest things to remember about lectures. Taking a lecture requires a great deal of learning and re-learning concepts outside of scheduled class time; so, be ready to extend this class outside of its regular hours. You may want to check out these tips on how to take notes in a college lecturebefore your first day of class! The Lengthy Once a Week Discussion: If you are going to be absent for a class, do your best to make sure its not this one. Since it occurs only once a week, it will most likely be around 3 hours long. As draining as that can be, it is incredibly important that you attend each session so you can stay well on track. You should put a stronger focus on taking as many detailed notes as you can in this class since your time in it is limited. Tests will come around quicker than you expect and the syllabus objectives will fly by. These particular class sessions may not be the most exciting, but you must bring yourself to pay full attention during each one or else you will easily fall behind. Just think, instead of splitting it up into the 3 Days a Week Discussion, you are getting it all done at once. On one hand, that can be stressful but on another hand, that can be quite relieving. Here are some great tips on how to participate in a class discussion. The Lab: Usually a science-related course, labs are exactly what they sound like. You cannot come to these classes half-asleep because you truly need to be alert to complete these tasks successfully. These assignments involve more active and physical work than writing up short-answer responses or analyzing a chapter in a novel. While in other classes, you spend a lot of time listening, labs require a lot of doing. Some of the concepts you will be quizzed on will involve things you can only learn by completing the lab projects attentively. Since those projects can often only be done in class at those designated times and not figured out on your own later, it is best to always save more than enough energy for this course. The Relaxed Elective: These are always a nice break in the middle of a hectic schedule. Especially since you probably wont have a chance to take one of these every semester, the semesters you do get to work one into your schedule will make you extra thankful. It is important to clarify that you should choose electives that do fulfill some graduate requirement without a doubt, you will find one that covers a credit you need. There are two simple things to remember about these courses. First off, enjoy. You could be taking yoga, kickboxing, modern dance, painting - there is no end to random college electives and there is no pressure. Just have fun and maybe youll even get something out of it. Secondly, however, you need to watch out for easy ways to mess up your grade. Most of these classes are seen as easy As and therefore students tend to put them on the backburner and give little to no attention to the syllabuses. Yet, random rules such as more than one unexcused absence will resu lt in an F or final paper on what you learned in Yoga due the last day of class are thrown in there to make sure students pay attention. Dont fall into that trap of forgetting that there is some work involved and protect your grade!

How To Prep For the ACT Reading Section

How To Prep For the ACT Reading Section ACT Reading section: 40 questions, 35 minutesFor most students, reading less is better. This might seem counterintuitive, but most people take too much time reading the passage and then remember too little of it. The better option is to attack the passage strategically so that you dont have to read the entire thing, or if you do, read it in small chunks. Look at the questions and see if there are any key words. These include proper nouns, dates or other numbers, or definition or category words. Try to find that key word in the passage and then read the couple sentences around it. Keep in mind that any words that are capitalized or numbers will pop out easily in the passage. Dont be afraid to underline these words or write yourself reminders in the margins! This way, you will know where to go back and look if a future question centers around the same issue. Also try to strategize the order to do the passages. The ACTReading always has four passages and they are always in the same order. Prose Fiction: This passage is an excerpt from a book or a short story. The key word strategy works to varying degrees on this passage. Sometimes the best option is to read this because stories are easier to remember than a collection of facts. Social Sciences: Covers issues like sociology, or how people work in history, or psychology. These passages might talk about a government program, or how people react to technology, or how reporters cover a story. Contains facts. Humanities: Includes things like music, art, literature, and entertainment. A passage could be about jazz, or the modern art movement, or a specific television show. Natural Sciences: This is a science passage that usually uses technical language and covers some kind of scientific discovery or movement. Start with the section you feel the most comfortable with and understand the best. Save the hardest for last. That way, if you run out of time, you will have to guess on a passage where you might have guessed on several questions anyway. Remember: if its not in the passage, dont pick that answer! Some answers sound good but are not actually in the passage. Find a sentence or word that backs up your answer choice. The more you can justify the choice, the more likely it is to be correct. If you want to ensure you are prepared for this section, consider taking some ACT practice tests,reviewing aprep book, or meeting with an ACT Reading tutorto enhance your skills.

Definition of Alternate Interior Angles

Definition of Alternate Interior Angles Definition of alternate interior angles helps in understanding the concept about the alternate interior angles. Alternate interior angles are the angles formed when a line (Transversal) crosses two lines that are parallel to each other. They are pair of angles inside the parallel lines and on opposite sides of the transversal. Alternate interior angles are congruent (same). In real life, a good example to understand pairs of angles is a window plane. From the figure a and b are alternate interior angles. 1 and 2 are alternate interior angles So, a = b and 1= 2 Example 1: If angle a is 450 and angle 2 is 1350 then what is angle b and angle 1? Solution: As angle a and angle b are alternate interior angles, they are congruent. = So, a =b =45 = As angle 1 and 2 are alternate interior angles, they are also congruent. = So, 1 =2 =1350 Example 2: If angle 4 = 50 degree, find the measure of angle 2 and angle 3? Solution: The given angle 4 is equal to 500. = Since, Angle 4 is the interior angle and its alternate angle is 2. = Therefore, 4 = 2= 500 = Another pair of alternate interior angles is angle 1 and 3 = Angle 4 and 1 lie in the same line. So, sum of their angles = 1800 = Therefore, 50 + 1 = 180 = Then, 1 = 1300 = Since angle 1 and 3 are alternate interior angles = Therefore, 1 = 3 = 1300

Difference between Like and As - English Lesson via Skype

Difference between Like and As - English Lesson via Skype Difference between Like and As is one of the common mistakes made by ESL students. So if youre planning to take English proficiency tests in the near future, you will find this post useful.You can either watch a short video lesson or scroll down and read the transcript below.There is also a short quiz at the end to help you better remember the difference between Like and As. Difference between Like and As - Transcript Hi there and welcome to this video and our Channel.This is Harry from englishlessonviaskype.com and youre really really welcome.Today were going to talk about the difference between LIKE and AS.They often get confused, so hopefully by the end of this video youll understand the differences and how to use them a little better.And as always, Ill give you some examples as we go through it.Were using LIKE when were talking about something that is similar to or the same as. Okay. Often we use it when were comparing people. Okay.This boy, he is like his father. He is like hisgrandfather.He is like his older brother.So he is similar to them or the same as them in terms of perhaps his stature, his build, his looks, his characteristics.Hes not exactly the same, of course, but he just looks like or acts like or behaves like them.Somebody lives in an amazing house. Big, grand, spacious.Oh this house is like a castle. Its not literally or exactly a castle. It doesnt have parapets and a drawbridge , of course. But its big and its spacious and expensive so somebody can say:Wow, what a house! It looks like a castle.Okay. So when were using like we dont mean its exactly the same. Were using it as an example of an exaggeration and its just to give it some sort of emphasis. Okay.For example, if were going to a disco and were going for dance on the floor and we say to our friends:Be really careful, that floor is very slippery. Its like dancing on ice.Now, youre not literally dancing on ice but the floor slippery so your legs are going in all directions so its like dancing on ice.You look out the window and the weather is really cold. For example, this morning when I woke up it was actually snowing and its the 14th of April and snowing.   I said:Wow, I hate weather like this!Meaning cold, not so so warm, a little dark, overcast, particularly at a time of the year when youre expecting warmer weather. Ok.  So when we use LIKE its as a preposition, its always followed by a noun so that s one way you will recognise it.Its like a castle.Like dancing on ice. Always followed by a noun. Okay.Hes like his father.He is like his grandfather. Difference between Like and As Don't keep this to yourself, tell the world: When we use AS we usually use it before the subject and a verb. So this is how you will recognise AS.For example:Please leave everything as it   was.Please leave everything as it was.It is the subject. Was is the verb.Please do it as I showed you.So if youre helping somebody at work and theyre looking for some help and you help them for example with their spreadsheet youll say:Please do it as I have showed you.So I is the subject. Have showed is the verb.So immediately you can recognise when you use AS.When we want to use AS also as a preposition? Well, we usually use it when were talking about real things.So he worked during the summer as a laborer.Ok. So its exactly that thats the work he had. He worked as a laborer.He worked as a sales assistant in the garage.Exactly the job he had as a sales assistant in the garage.When he left university he worked as a doctor in the medical centre. So as a doctor. That was literally his job.He worked as a teacher.As a teacher, as a banker, so al ways using asto describe exactly what they did and its very relevant when we we talk about peoples work.Okay. Its important to understand those differences.So LIKE similar to the SAME AS always followed by a noun.And then when were using AS it is always followed by subject and the verb.And when were talking about the preposition, usually were telling people exactly what it is.So LIKE its similar to but obviously not the same.Like a castle so theres a slight exaggeration there.But as a waiter, as a doctor then there are no exaggerations, exactly the way it was intended.Okay. So thats to describe the difference between like and as.And hopefully youve got an understanding how to recognise them and how to use them.We would really love it if youcan join us on www.englishlessonviaskype.com and as always please subscribe to our Channel.Make sure you hit the bell that they the notification button because this in this way you will be notified when theres a new video waiting for you.We have six online English language courses.Yes, six English language courses waiting for you thereand theres a discount coupon in the description below so youll be able to find something that suits you and this includes the most recent course that weve launched.Which is 73 Common Mistakes that people make in learning English.

Why I volunteer - Alliyahs story

Why I volunteer - Alliyah's story Alliyah volunteers through the Tutorfair Foundation's “Tuition for all” programme, where tutors help students who are struggling at school and cannot afford private tuition. Here, Alliyah shares her uplifting story of overcoming her fear of tutoring to discover the rewards and fun that come with volunteering alongside the Tutorfair Foundation. I distinctly remember how terrified I was on my first day of tutoring. The expected anxiety of ‘what if the students hate me?’ was tirelessly running through my mind the whole day. But as I left the session that day I left with a smile on my face. They didn’t totally hate me! Success! I looked through their work like a proud mother, excitedly planning the next week's session in my mind. That’s not to say tutoring was always easy, it had its rough moments. It also involved a LOT of effort and motivation, because if I wasn’t motivated my students wouldn’t be, and if I wasn’t prepared with resources and backup resources then my lessons were likely to spiral out of control. Personally, I don’t want to be a teacher. I think it takes a special kind of patience and selflessness to teach high school students. But despite this, I’m proud of my Tutorfair experience. I conquered a huge fear; I took time out of my packed schedule and enjoyed planning/teaching. It was the rare moments when one of my students would look at me and say ‘miss, you make me want to learn’ or see that spark in their eye when they accomplished something they may have struggled with before. Little moments like that make the experience very rewarding. Tutorfair also provides you with a lot of personal support, as well as training. We had a program manager who was with us every step of the way, emailing us with helpful resources or just general words of encouragement. For a first time tutor like myself it was an invaluable form of support! I would recommend tutoring with Tutorfair to anyone, not just those interested in teaching. The programme requires you to take responsibility for lesson planning, allowing you to study your students carefully, their ability and the little things they struggle with. In this situation you are the responsible adult, and your students expect you to provide them with support. That in itself is a maturing experience. So yes, tutoring can be scary, and tiring, and sometimes emotionally draining. But it can also be rewarding and fun and character building. I had never tutored before, but I’m glad I chose Tutorfair. I felt safe and supported during the new venture I was undertaking. Alliyah R - Paddington Academy Volunteer - English

How to Stand Out as a Scholarship Applicant

How to Stand Out as a Scholarship Applicant Image via Isorepublic.com Follow directions and ensure you are qualified It’s amazing the number of applications that are disqualified because the applicant did not follow the directions or the prompt (or because they missed the due date!). Not answering the prompt completely can cause you to miss out on the award! This mistake can easily be avoided if you take a few extra minutes to read the prompt and ensure that your essay responds to everything the prompt asks you. If it helps you, make it into a checklist and check off questions as you address them in your essay. That way, you will know exactly what the instructions are asking of you, and you know that you’ve answered all of them. Also, applications can be discarded when the applicant is not qualified. For example, if the scholarship award is only for graduate students, don’t apply for it if you are not a graduate student. Don’t waste your time applying for a scholarship that you are not qualified for. Instead, spend that time searching for a scholarship award that you ARE qualified for. These are simple mistakes that can be avoided if you only spend a few extra minutes making sure that you’ve responded to the prompt entirely and that you are eligible for the award. Submit a unique essay It’s tempting to submit the same essay to multiple scholarship applications, but I would encourage against this. Using the same essay for multiple competitions is a risky move. Instead, take the time to tailor each essay for the specific prompt. When you submit a unique essay, it will show that you are passionate about the subject, and it will impress the scholarship application judges. You will stand out among those who used the same essay for multiple competitions. For this reason, submit a unique essay each time you enter a scholarship competition. Yes, it requires extra effort, but it is well worth it. Have someone else review your essay Whenever you write something, it’s a good idea to get someone else to read it over, too. Sometimes, we get so used to reading our own writing that we overlook some minor mistakes we make. But if you have someone else reading your work, they will catch these mistakes and will give you feedback to improve your essay. Also, they might give you some ideas that you might not have thought of on your own. Go to your school’s writing center or ask your English professor to double check your essay. Their feedback will be very valuable and will increase your chances of winning the award. Submit it (and start writing it) earlier, not later It’s not always true that your chances of winning a scholarship essay contest will increase if you submit your essay earlier. Still, it’s definitely worth the extra effort to get your application in earlier rather than later. It will give you peace of mind and relief to know that your application has already been turned in. It will even give you more time to look for the next scholarship essay contest to enter! Starting it early is a good idea, too. The earlier you start writing the essay, the more time you have to craft a unique essay. You need time to write a winning essay, and starting earlier will give you that time. You won’t need to modify an existing essay you already have, because you will have time to tailor an entirely new essay to this specific contest prompt. Submitting your scholarship essay earlier rather than later might not increase your chances of winning, but it will give you great relief. The same goes for beginning the essay writing process earlier. Scholarships are a common way for students to pay off their college tuition. However, the scholarship application process can be a bit tricky, especially if an essay is involved. Still, as long as you give yourself enough time, have someone else proofread the essay, and follow all the directions, you have a good chance at standing out as a scholarship applicant.
