MathLiveHelmholtz free energy
Defines the Helmholtz free energy as the internal energy minus the product of temperature and entropy. It is used to find the maximum reversible work obtainable from a system at constant temperature and volume, and it tends to a minimum at equilibrium under those conditions.
