# Entropy change for isothermal process

1. Given that the Gibbs function is:

G=H-TS (H=U+PV dU=TdS-pdV etc.)

And since the Gibbs function is a "state function" and forms exact differential, find a simple expression for the change of entropy with respect to pressure for an isothermal process with an ideal gas:
