Suppose you have two objects of unequal size, A and B, in thermal contact with one another. Model object A as having 20 "bins"
(green circles) for thermal energy and object B having 5 "bins" (green circles) for thermal energy. At the start, A has no "packets" of
thermal energy (all bins are empty) and B has 5 "packets" (all bins are full) as shown schematically in the figure above. Note that only
a single microstate is shown in this figure, but that for this specific macrostate, there is only a single microstate. For the following
questions report the answers for the entropy in units of k_b. That is, if you get 2.30 k_b, just put 2.30 in the answer box.
(a.) What is the initial entropy of object A?
