For Josiah Willard Gibbs, American physicist.
- (physics, chemistry, thermodynamics) The difference between the enthalpy of a system and the product of its entropy and absolute temperature: a measure of the useful work obtainable from a thermodynamic system at constant temperature and pressure.
- and where G is Gibbs free energy, H is enthalpy, T is temperature, and S is entropy.
difference between the enthalpy of a system and the product of its entropy etc.
