comment

  • A thermodynamic potential that is amount of energy of dynamical entity that is available for doing useful work at a constant temperature and volume.

discussion

  • For dynamical entity the amount of Helmholtz free energy, A, is the difference between the entity's internal energy, U, and the product of its temperature, T, and its entropy, S; i.e, A = U-TS.
