gibbs function

noun

1. the thermodynamic function of a system that is equal to its enthalpy minus the product of its absolute temperture and entropy: a decrease in the function is equal to the maximum amount of work available exclusive of that due to pressure times volume change during a reversible, isothermal, isobaric process.

noun

1. a thermodynamic property of a system equal to the difference between its enthalpy and the product of its temperature and its entropy. It is usually measured in joulesSymbol: G, (esp US) F Also called: Gibbs free energy, free enthalpy Compare Helmholtz function
