A van der Waals gas undergoes an isothermal expansion from specific volume v1 to specific volume v2.

(i) Calculate the change in the specific Helmholtz function for this process.
(ii) Calculate the change in the specific internal energy U for this process in terms of v1 and v2 using uqation F=U +T(partia F/ partia T)V.
