Change: thermodynamics,thermodynamics, the Gibbs free energy is the portion of energy of an isothermal, isobaric system that can be converted into useful external work. The conception was introduced by American mathematical physicist Willard Gibbs in 1873 and called by him "available energy". [1] In chemistry,chemistry,   View changes from previous version.
