The two main types of this are defined as either the internal energy or enthalpy minus the product of temperature and entropy.
The Flory-Huggins model can be used to derive this quantity. Differentiating this quantity with respect to volume yields pressure, while differentiating with respect to number of particles yields chemical potential, and differentiating with respect to temperature yields entropy. The two main types of this are defined as either the internal energy or enthalpy minus the product of temperature and entropy. For 10 points, name this thermodynamic quantity that denotes the amount of work available in a system and comes in Helmholtz and Gibbs varieties.
The Flory-Huggins model can be used to derive this quantity.
