Homework Statement
How do you express work in an isothermal increase of pressure of a solid in terms of the initial and final pressure?
Homework Equations
van der waals equation
W=Integral of PdV
(P-na/v^2)(v-nb)=nKT
P=pressure
V=volume
n=number of molecules(constant)
T=temperature(constant)
The Attempt at a Solution
d/dV[(P-na/V^2)(V-nb)=nKT]*
The problem here is that dP and dV are very hard to separate so it is hard to substitute dP in W=integral of PdV.
