Consider a system of two Einstein solids, A and B, each containing 10 oscillators, sharing a total of 20 units of energy. Assume that the solids are weakly coupled, and that the total energy is fixed.
(a) How many different macrostates are available to this system?
(b) How many different microstates are available to this system?
(c) Assuming that this system is in thermal equilibrium, what is the probability of
finding all the energy in solid A?
(d) What is the probability of finding exactly half of the energy in solid A?
(e) Under what circumstances would this system exhibit irreversible behavior
