Problem 1. For the system of N spins (see the lecture notes), with energy e separating individual spin-down states from spin-up states, express the total internal energy U(T) of the system via its temperature T in equilibrium. Problem 2. For the same system of N spins, express its entropy S(T) via temperature T in equilibrium.
