2. Consider a macroscopic system of two blocks that are in thermal contact. The two-block system is isolated from the rest of the universe. Initially, a hotter block is at a temperature TH and a colder block is at a temperature Tc. In the final state of the system, the two blocks are at the same intermediate temperature T.

Model - Entropy as a State Function Entropy, S, as with all other state functions like internal energy, E, and enthalpy, H, is a function of the state of a system. Because measuring the absolute state of a system more difficult than measuring the changes in its states, it is the change in entropy, ΔS, in which we will be interested. This means the only aspects that will interest us will be the difference in the final and initial entropies...

The system above has two distinguishable particles, each can be
in either of two boxes. The system is in thermal equilibrium with a
heat bath at temperature, T. The energy of the particle is zero
when it's in the left box, and it is
when it is in the right box. There is a correlation energy term
that increases the system energy by
