WebMay 31, 2024 · What happens to entropy when temperature increases and volume decreases? ΔS=q/T , so the higher the temperature, the smaller the change in entropy for the same amount of heat released or absorbed. ΔS=nRlnV 2 /V 1 , so if there is a decrease in volume the ln term will become negative, and there will be a decrease in entropy.
