(a) Find the entropy of a set of N oscillators of frequency as a function of...
Question:
(b) Let U denote the total energy nhω of the oscillators. Express the entropy as σ(U, N). Show that the total energy at temperature τ is
U = Nhω / ex(hω/τ)–1 (42)
This is the Plank result; it is derived again in Chapter 4 by a powerful method that does not require us to find the multiplicity function.
