Effect of temperature on entropy

Postby Elena Liu 2J » Fri Mar 15, 2024 9:31 am

According to delta S = qrev/T, when T increases, the change in S will decrease because they have an inverse relationship. But I thought that increasing temperature causes increasing vibrations and movements of molecules and entropy would increase? Can someone explain which thought process we use and in what situations?

hello,
so the equation you have provided is when everything is constant. For example, when ur volume is not changing and neither is your pressure. The correct concept is that yes temperature is changing (increases), which causes entropy to increase.
hope this helps!
