The final equilibrium state will thus be the state of maximum possible entropy. After attaining this maximum possible value, the entropy will remain constant. We can take S to be a function of U, V and N. The system, starting in an arbitrary state, adjusts U, V and N among its different parts and constitutes itself in such a way as to maximize entropy.
