Question

1. Suppose a system composed of two subsystems that we call S1 and S2 in thermal contact.

Assume further that the wall separating the two subsystems is movable and impenetrable at particles.

(a) Define the macrostate of the system.

(b) Through statistical considerations find the equilibrium condition for such a system.

(c) Determine the physical significance of the thermodynamic equilibrium parameters.

(d) If the exchange is such that the three macroscopic parameters (E, V, N) are variable, find the new equilibrium condition.
