Solution: Click For PDF Version (a) and (b) When heat is conducted through a brass rod, there is no change in the entropy of the rod as the thermodynamic state of the rod does not change during the process if heat conduction. Change in entropy arises because of heat exchanges taking place at the reservoirs at the ends of the rod.
Heat loss at
the reservoir at temperature of
The change in entropy of the system comprising of the two reservoirs and the brass rod will be
