WebThe Maxwell Relations (Eq. 1) interrelate volume, pressure, temperature, and entropy ( V, P, T, S) of a thermodynamic system. An advanced version (Eq. 2) replaces P and V with the stress tensor, σ, and the natural (Hencky) strain tensor, ε, times reference volume, V0. The basic Thermodynamic Maxwell Relations are. WebMaxwell Relations. The above result suggests that the natural variables of internal energy are S and V (or the function can be considered as U ( S, V) ). So the total differential ( d …
