Chapter 12, Problem 10E

Consider the system shown in Figure 12.9. What is the change in entropy for the process where the energy is initially associated only with particle A, but in the final state the energy is distributed between two different particles?

Figure 12.9 This shows a microstate model describing the flow of heat from a hot object a cold object (a) Before the heat flow occurs, the object comprised of particles A and B contains both units of energy and as represented by a distribution of three microstates (b) If the beat flow results in an even dispersal of energy (one energy unit transferred), a distribution of four microstates results (c) if both energy units are transferred, the resulting distribution has three microstates
