similarly, expressions for other thermodynamic potentials
pressure:

p = - {(\frac{\partial F}{\partial V})}_{T}

enthalpy:

H = U + p V

gibb's free energy:

G = H - T S

$Z$ can be used to find $U$ and $F$ , and hence find $S :$

S = \frac{U - F}{T}

also, heat capacity:

C_{V} = {(\frac{\partial U}{\partial T})}_{V}
