For an ideal gas with constant heat capacities, show that: (a) For a temperature change from T¡ to T2, AS of the gas is greater when the change occurs at constant pressure than when it occurs at constant volume. (b) For a pressure change from Pı to P2, the sign of AS for an isothermal change is opposite that for a constant-volume change.

![Problem 5
For an ideal gas with constant heat capacities, show that:
(a) For a temperature change from T, to T,, AS of the gas is greater when the change
occurs at constant pressure than when it occurs at constant volume.
(b) For a pressure change from P1 to P2, the sign of AS for an isothermal change is
opposite that for a constant-volume change.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F41d0ba29-414e-49b0-a26d-5ca24e7756e5%2F6f56ec10-443e-40c2-b0ba-358b5f91afc7%2F7hqugt_processed.png&w=3840&q=75)
