Why does heat increase entropy?

445 viewsOtherPhysics

My brain can’t understand this at all. In an isolated system with cold molecules on one side and hot molecules on the other, I understand how the heat of this system balances with time, but it’s confusing to me that a system with a more evenly distributed temperature has increased randomness when it appears that there’s more order.

This feels like it should be simple, but my brain simply isn’t getting it, no matter how many analogies or examples I read. I’ve got to be missing something very simple, and that’s why it’s so frustrating that I don’t understand it. This is seriously stressing me out.

Because the more energy a system has, the more things that energy can be doing — the more states things can be in. If there is little energy in a closed system, there fewer possible variations of things.
