Gibbs Function

</dt>
A mathematically defined thermodynamic function of state, which is constant during a reversible isobaric-isothermal process. Also called Gibbs free energy, thermodynamic potential. Compare Helmholtz function. </dd>
In symbols the specific Gibbs function g is g = h - Ts where h is specific enthalpy; T is Kelvin temperature; and s is specific entropy. By use of the first law of thermodynamics for reversible processes, dg = -s dT + dp. </dd>
