WebApr 9, 2024 · Helmholtz Free Energy Equation. A = U - TS .. eqⁿ1. U is the internal energy in Joules, T is the absolute temperature in Kelvin, and S is the final entropy in Joules per Kelvin (JK⁻¹). A stands for 'Arbeit' meaning work and is minimized to the equilibrium. Hermann von Helmholtz formulated it. WebThe internal energy is the mean value of the system's total energy, i.e., the sum of all microstate energies, each weighted by its probability of occurrence: This is the statistical expression of the law of conservation of energy . Interactions of thermodynamic systems. Type of system. Mass flow.
