1. Three-level system Consider a system of non-interacting particles at temperature T where each particle has only thre energy levels: -ɛ, 0, +ɛ (These could be for instance atoms with spin s=1 in a magnetic field). Write the partition function of a single particle - Zsp, the average energy per particle, & and the entropy S of the particle. a. b. Find the values of , and S in the limits of ße →0 and Be →∞. Could we have anticipated these results in advance without any calculation? C. The result for S in the classical limit (Bè →0) corresponds to the expression S = k ln which we got in the case of a system where all the states have equal energy. Why is this so? d. Without any calculation, what should be the value of Cy in the two limits above?
