Webpartition functions of the two systems coincide with each other at these two temperatures. Since the Helmholtz free energy AH obeys AKT ZHB log( ) , where KB is the Boltzmann constant, this is the same as saying that two systems are put in the same equivalence class if their Helmholtz free energies coincide at these two temperatures. WebII.A.1 Equilibrium Statistical Mechanics. The thermodynamic equation of state of a system can be derived from an expression that relates the Helmholtz free energy AN ( T, V) to the microscopic properties of the system, where T is the thermodynamic temperature (degrees Kelvin), V is the volume, and. is the canonical partition function.

G ( N, P, T) = − 1 β ln Δ ( N, P, T) This can be shown in a manner similar to that used to prove the A = − ( 1 / β) ln Q. The differential equation to start with is. G = A + P V = A + P ∂ G ∂ P.
