freie Enthalpie
type: QuantityKind
description: $\textit{Internal Energy}$ 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.
