Object A and object B are two identical microscopic objects. Figure 12.54 below shows the number of ways to arrange

energy in one of these objects, as a function of the amount of energy in the object.

(a) When there are 1.0 × 10−20 joules of energy in object A, what is the entropy of this object?

(b) When there are 1.4 × 10−20 joules of energy in object B, what is the entropy of this object?

(c) Now the two objects are placed in contact with each other. At this moment, before there is time for any energy flow

between the objects, what is the entropy of the combined system of objects A and B?
