example 9.2

The example asks you to find the change in entropy when a gas is heated at a constant volume. You have to use the equation deltaS=C ln(T2/T1), but I was wondering why you don't have to account for a change in pressure... or is there no change in pressure?

For that example, you would use pressure to calculate moles of the substance. Also, I don't think there was any change in pressure.

Can someone elaborate on whether or not there is a pressure change, and if so how can you tell?
