Consider a model thermodynamic system in which the allowed (nondegeerate) energy levels are 0, E, 2E, 3E. The system has three indistinguishable bosons and a total energy U=4E.
A) Determine how many macrostates are possible.
B) For each macrostate how many microstates are there? Explain why this is the case.
C) Compute the average occupation numbers for each energy level.
