    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.

  • @emilybarker7475

    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.

    • @RongSpelingz

      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 Рік тому +6

      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.

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!

      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.

I guess the definition “entropy is a measure of how spread out energy is” is much less confusing than the “disorder” definition

    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!

    So basically, the energy is kids, the container is a school, and entropy is the "end of day" bell. All those kids just rush out. (Bonus points if it's a Friday.)

    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.

    Conclusion :
    - Entropy can happen at everytime.
    - Chances of entropy if it is spread out is high as energy will move around and will move to other object.
    - When both of the entropy of the object is going to stabilise, both object will have same temperature.
    - It have 13% chances for one object to be hotter and another object to be colder as energy will move around... and theoritically will only happen in vacuum because the energy will also lost to the air surrounding...
    - Quanta is the unit of energy...
    - More energy higher the temperature.
    ....
    Anyway for my own opinion I think that entropy is related to probability and combination and even permutation meaning it is related to additional mathematics. More I think that the energy will be stabilise or will be equal in each object all is because of the probability of the entropy.
    For real I only understand most of the video but some I really do not understand it ... it could be 80% to 85% understand and 20% to 15% not...
    And wait my question here is...
    • will the size determine the entropy and the energy transfer between the bond and will effect the temperature changes in the object?
    • Will energy still move from colder to hotter one and will it only happen in vacuum or is it possible to happen at the normal environment with air?
    • Is Earth an example of entropy? And is Sun or other Star the example of entrophy?

    Also, this video's explanation on Entropy is honestly more confusing than what it originally was.
    Still a neat video though since I did understand it.
