WebFeb 25, 2024 · Gibbs free energy ( uncountable ) ( physics, chemistry, thermodynamics) The difference between the enthalpy of a system and the product of its entropy and absolute temperature: a measure of the useful work obtainable from a thermodynamic system at constant temperature and pressure. and WebAnswer: Think of entropy S as the price per degree K of using energy to do mechanical work. Enthalpy, U + pV, is the scary name given to the internal energy U of a system … WebGibbs originally called it available energy and that is a good term because it is the energy associated with a chemical reaction that is available (or you could say free) to do work, assuming constant T and P. lane and lenge florist west hartford ct
