Thermodynamic free energy - Wikipedia

WebSeveral free energy functions may be formulated based on system criteria. Free energy functions are Legendre transforms of the internal energy. The Gibbs free energy is given by G = H − TS, where H is the enthalpy, T is the absolute temperature, and S is the entropy. H = U + pV, where U is the internal energy, p is the pressure, and V is the ... In thermodynamics, the Gibbs free energy (or Gibbs energy as the recommended name; symbol ) is a thermodynamic potential that can be used to calculate the maximum amount of non-volume expansion work that may be performed by a thermodynamically closed system at constant temperature and pressure. It also provides a necessary condition for processes such as chemic… WebWe can further investigate the derivative of the intrinsic free energy with respect to time and obtain dF dt = −σ 4 dx ∇ ln (P/P ss ) · D · (∇ ln (P/P ss ))P ≤ 0.
