WebLars Erik Øi Webd E = c ( T) d T. We can proceed likewise with enthalpy: d H = d E + d ( P V) = c ( T) d T + P d V + V d P. For a solid, d V = 0 for a fixed amount of matter, and furthermore d E ≫ V d P, thus. H = E. . There is nothing wrong in these concepts (the thermodynamic potentials) for liquids and solids. Share.
