Entropy Change Relating to Temperature

Postby Jessica Chern 1H » Sat Jan 28, 2017 5:03 pm

I know that ΔS = q/T, so I understand (using the equation) that the entropy change is smaller at higher temperatures. But why is this so, conceptually?

Entropy is less at smaller temperatures, because the more heat you give to a gas, for example, the more excited and random the atoms become. Think about it like heating popcorn. At low temperatures, you are pretty sure where the popcorn kernels will be. But at higher temperatures, when the popcorn pops, it goes all over the place and creates a sort of chaos.
