Problem 36P
Consider an Einstein solid for which both N and q are much greater than 1. Think of each oscillator as a separate “particle.”
(a) Show that the chemical potential is
(b) Discuss this result in the limits N ≫ q and N ≪ q, concentrating on the question of how much S increases when another particle carrying no energy is added to the system. Does the formula make intuitive sense?

Step 1 of 5
Part (a)
The expression for the solid which contains oscillators and energy units is,
The entropy of a system can be expressed as,
