For 10 points, name this measure of energy denoted H.
In Flory-Huggins theory, this quantity equals the product of kT times the volume fractions of polymer and solvent times the interaction parameter. The value of this quantity for steam is plotted on the y-axis of a Mollier diagram. The derivative of "G over T" with respect to T equals minus this quantity over T squared, where G and T are Gibbs free energy and temperature. The change in this thermodynamic (*) potential is zero for ideal mixing. The temperature derivative of this quantity gives the constant-pressure heat capacity. Internal energy plus pressure times volume gives this quantity, whose change for sublimation equals the sum of its change for melting and its change for vaporization, a fact which directly follows from Hess's Law.
