Third Law of Thermo Definition of Gibss (G) and Helmholtz (A) Free Energies: G = H - TS A = U - TS Differentials dU, dH, dA, dG and dS dU = -PdV + TdS dH = VdP + TdS dA = -PdV _SdT dG = VdP -SdT dS = (Cp/T) dT - α VdP or dS = (Cv/T) dT + ( α / κ T ) dV The second law of thermo expressed with G for systems at constant P & T. The second law of thermo expressed with A for systems at constant V & T.
