Question

Problem 3.35. In the text I showed that for an Einstein solid with three os- cillators and three units of energy, the chemical potential is μ = -e (where e is

the size of an energy unit and we treat each oscillator as a "particle"). Suppose instead that the solid has three oscillators and four units of energy. How does the chemical potential then compare to -e? (Don't try to get an actual value for the chemical potential; just explain whether it is more or less than -€.)
