\(G = H - T \cdot S\), where \(H\) is enthalpy, \(T\) is thermodynamic temperature and \(S\) is entropy.

"Gibbs Energy} is one of the potentials are used to measure energy changes in systems as they evolve from an initial state to a final state. The potential used depends on the constraints of the system, such as constant temperature or pressure. \textit{Internal Energy} is the internal energy of the system, \textit{Enthalpy} is the internal energy of the system plus the energy related to pressure-volume work, and Helmholtz and Gibbs free energy are the energies available in a system to do useful work when the temperature and volume or the pressure and temperature are fixed, respectively. The name \textit{Gibbs Free Energy" is also used.
