### More Entropy vs. Less Entropy

Can someone please explain why more entropy is favorable over less entropy? I can't seem to grasp the logic behind the idea that disorder is more favorable than order. Thanks.

I'm not sure if we've gone over this in class, but I think the principle of minimum energy and the entropy maximum principle should help you understand this concept more! Also, I think referring to entropy as disorder is probably causing more misunderstanding about this topic.

### Re: More Entropy vs. Less Entropy

Dr. Lavelle has been making a point to avoid using the word "disorder" when discussing entropy, so I believe avoiding that terminology might help with understanding it. Based on the two principles mentioned above, a system is stable when the internal energy is at its minimum and the entropy is at its maximum. You can think of it as resulting in a greater negative change in free energy which is preferred, but looking up those two principles will give you a more specific understanding. Hope that helps!

Yes, I think when Dr. Lavelle says disorder it gets a bit confusing.

Basically, entropy increases when the temperature increases. Therefore, something with larger volume and lower pressure has more entropy; whereas something with lower volume and the larger press has less entropy.
