Gibbs function
noun
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.
Also called
Gibbs free energy,
thermodynamic potential.
