Homework Statement
A solid has energy (for one mole):
##U_1 =\frac{S^2}{a_1}+b_1V(V-2V_0)##
Write H, F, and G in terms of their proper variables.
Homework Equations
Maxwell's relations and
H=U+PV
F=U-TS
G=U-TS+PV
The Attempt at a Solution
[/B]
H, for example:
I have tried writing dV as a sum of partial derivatives times total differentials:
##dV=\frac{\partial V}{\partial S}dS+\frac{\partial V}{\partial P}dP##
I have no idea how to get V in terms of S and P.
I have similar problems for the other cases.
Thanks for any help!
