Show that CP and CV may be related to each other through quantities that may be
determined from the equation of state (i.e. by knowing V as a function of P, T, and N)

Spin-statistics theorem
As we discussed in P301, all sub-atomic particles with which we have
experience have an internal degree of freedom known as intrinsic spin, which
comes in integral multiples of hbar/2 (i.e. h/4, so it has dimensions of
