The simple thing is to write everything as a system of ordinary differential
equations:

dE/dV + dE/dT DdT/dV = - P

consider now the unknown function T depending on the variable V , with the
initial point T(Vi) = Ti and integrate evrything in the interval (Vi,Vf)
using NDSolve.

I do not have mathematica at the moment but you should write something of the
kind:

NDSolve[ dE/dV + dE/dT T'[V] = -P , T[V] , {V,Vi,Vf} ]
