We have calculated E = U – U(0), which is the internal energy referenced to the value, U(0) at absolute zero (T = 0 K).
We can now calculate the entropy, S = k ln W
Now recalling the definition of the Boltzmann distribution
ln pi = - bei – ln q
The entropy is,
.
The entropy can be expressed in terms of the system partition function Q
.
