Question

Problem 5.1 A thermodynamic system consists of N spatially separated subsystems. Each subsystem has non-degenerate energy levels of energy 0, $varepsilon$, $2varepsilon$ and $3varepsilon$.

Calculate the partition function, the mean energy and the entropy of the thermodynamic system. Problem 5.2 Repeat problem 5.1 for the case when the degeneracies of the energy levels of energy 0, $varepsilon$, $2varepsilon$ and $3varepsilon$ are 1, 2, 4 and 4 respectively. Problem 5.3 The partition function of a system is given by $log Z = aT^4V$ where a is a constant, T is the absolute temperature and V is the volume. Calculate the internal energy, the pressure and the entropy.
