4.6 Exercise 7

Avg difficulty 2.5

A metal rod is used to conduct heat between two reservoirs at temperatures ThandTc,T_{\text{h}} \text{and} T_{\text{c}} , respectively. When an amount of heat Q flows through the rod from the hot to the cold reservoir, what is the net entropy change of the rod, the hot reservoir, the cold reservoir, and the universe?
