The table includes macrostates characterized by 4 energy levels (&) that are
equally spaced but with different degrees of occupation.
a) Calculate the energy of all the macrostates (in joules). See if they all have
the same energy and number of particles.
b) Calculate the macrostate that is most likely to exist. For this macrostate,
show that the population of the levels is consistent with the Boltzmann
distribution.
