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.

Origin of Gibbs function

named after J. W. Gibbs
