An assembly of 20 distinguishable particles is to be distributed among three nondegenerate energy levels with energies 0, &, 2. The system is isolated and the total energy of the assembly is 56. Let us specify a macrostate by the three numbers: No, N1, N2, the number of particles in each energy level. For example, one such macrostate is (17, 1, 2) denoting 17 particles in the ground state, 1 particle in the first excited state, and 2 particles in the highest excited state. (a) Determine the other 2 macrostates. (Give your answer as either diagram, or a set of three numbers No, Ni, N2 for each macrostate) (b) What is the probability of each of these three macrostates occurring? [for three probabilities - one for each macrostate] (c) What is the entropy of this assembly
