a.A simple system has two states with energies 2E and 4E. What
is the canonical partition function of the system at temperature T,
if E = kT? (Hint: the canonical partition function applies when the
chemical potential, μ = 0.)
b.Consider a gas containing 4.0 × 104 rubidium atoms,
each of mass 1.5 × 10-25 kg, confined to a volume of 2.5
× 10-14 m3. To what temperature must it be cooled for
the effects of indistinguishability to be ignored...
