There’s a concept that’s crucial to chemistry and physics. It helps explain why physical processes go one way and not the other: why ice melts, why cream spreads in coffee, why air leaks out of a punctured tire. It’s entropy, and it’s notoriously difficult to wrap our heads around. Jeff Phillips gives a crash course on entropy.

Entropy is everywhere, even in our daily life. We don't realize it. For example, there are two libraries A and B. Both these libraries contain exactly the same number of books. All the titles available in library A are available in library B as well. Imagine that library A is well stacked and library B is just a huge pile of books and all the books are just dumped. As per the first law of thermodynamics, both these libraries are equal, (energy is conserved). But anyone who wants to take a book and do some reading will prefer library A only, which is well stacked and ordered ( Less entropy). Library A has less entropy and more order. While B has higher entropy and less order. We need to spend energy to bring it to order. So basically entropy is a measure of disorder or randomness. Higher the disorder higher the entropy. We cannot measure/calculate entropy for all the process or in other words it is very difficult to measure the entropy for some processes. There are equations for some standard engineering and chemical processes to calculate entropy. If entropy associated with a process is very high, the process tends to have low efficiency.

I think this was the best explanation of entropy I've seen. I always hated when professors described it as disorder to me because that begs the question, 'well what is disorder?' That is why I am always so careful to describe the statistics of entropy to my first year chemistry students. My one suggestion for your video would be to talk about translational entropy instead of vibrational/rotational energy because students tend to have a very difficult time conceptualizing bond energy unless you explicitly describe it in more detail than just stored energy, whereas kinetic energy is more intuitive for them.

"I think this was the best explanation of entropy I've seen. I always hated when professors described it as disorder to me because that begs the question, 'well what is disorder?'" That has always been a bad definition to me also. "Disorder" is both subjective and even if it is disorder... we need another explanation about what disorder is. Leading us further and further away from understanding entropy.

@jasoncassidy492
@jasoncassidy492 11 месяцев назад
Not a measure of energy configurations at all. When Clausius defined entropy as the sum of infinitesimal changes in heat at temperature T, he was talking specifically about heat as a macro quantity. Entropy is a mathematical statement of the 2nd law of thermodynamics which determines the direction of heat transfer in a process. If the process is reversible, entropy is zero and if irreversible, entropy is positive. Simple stuff, actually.

Several years later a colleague questioned why he was repeating the said question. The professor replied that although the question about entropy is same all the time I simply change the answer! This video is an excellent example of how confusing entropy can get.

I heard it was Einstein and the exam was about general relativity or something like that. He would give the same questions. When other professors asked him to change his questions, he said answers are always changing. It's not that he's changing the answers, it's the scientific discoveries. Without science changing the answers, one professor cannot have different answers to the same question.

The thing is, even if the unlikely happens once, you're still rolling that metaphysical quintillion-sided dice over and over again and the next shift in energy is still more likely to spread out again than otherwise. So you probably will never have to worry about your coffee getting hotter on its own or the mug exploding at random.

If you look at the glass of ice in its small scale, you’ll probably observe that some of the “units” are getting some energy here and there, thus getting hotter in some places counter intuitively, but as you look at the bigger picture, that gets negligeable, and in the long term it will cool. Also it would need to happen repeatedly in order to cool down, since its a continuous process. Another thing to take account is that in the macro world it might have no chance to happen, since when reaching a certain amount of factors the thing gets too defined to act otherwise, for example kicking a ball: there might be a chance for some energy to spread more to the right or to the left of the ball, but actual no chance for the compound to move in the opposite direction, the chances might just be zero for that, since all thought there could be a set of possibilities, that set is not infinite, rather limited. The conclusion is that in nature, not anything can happen, a defined amount of things in a point in time can happen, of which I wonder a lot about its actual nature and functioning, real randomness etc. These are just some of my thoughts, hope to give insight not certainty.

Beautiful description of entropy. Yet I wonder, could we experimentally verify the change of entropy for unlikely processes? For example 1 molecule and see if it will heat up spontaneously? While the other will cool down.

This was a very good explanation. Entropy is a measure of uncertainty related to a random variable or message in information theory. Entropy is correlated with the quantity of messages or outcomes that a system is capable of producing, and as the quantity of messages or outcomes grows, so does the entropy.

Very well put explanation. But to sum up this video for anyone who finds this. Entropy: A term of thermodynamics that (in laments terms) talks about the statistical probability of energy dispersion (and does it in some incredibly confusing ways). I’ve gotten this questions as well, it isn’t a force or aspect like gravity in physics, like this video said entropy is just what we use to describe things, it itself doesn’t do anything.

So basically, Entropy is the measurement of the chaos, which means the measurement of the probability of energy configurations. The atoms that make up the body are linked by bonds, and Quantas (an energy unit) is stored in them. The quantas can move however they want inside the different bonds in the same body, each one of the positions of quanta configuration is called a microstate. When two bodies with a different number of quantas meet, the quantas move from one body to another creating many many many probable microstates, and some of those microstates indicate the same number of energy distribution. When calculating the number of microstates where two bodies achieve the same number of quantas in the end, it's always higher than the other potential configurations, and the bigger the object the less probable that a cold body will get colder after meeting a hot body, and that's why it never occurs, it's simply probability. Oh and ofc, energy is always conserved but never in the same entropy, the lower entropy is the more concentrated it is and the better quality it is. On the other hand if it's high, it's not really high quality. Now Let's talk about something more interesting, imagine having probability manipulation, isn't controlling entropy the best thing anyone can do ? Imagine bringing ice to a volcano and showing people the ice getting colder, how cool would that be.

The guy at the end definitely died when his energy “spread out”. With enough time, everything dies. That’s entropy. Even if that hot object got hotter, it wouldn’t be eternal, and it would eventually cool again. We as human base our lives and governing systems around people, beliefs, and current systems that are suspect to entropy. So there’s a seemingly long process of ebb and flow, though we, and civilization as we know it will eventually come to an end. Interesting stuff!
