A brass rod is in thermal contact with a constant-temperature reservoir at 127 'C at one end and a constant-temperature reservoir at 37.2 C at the other end. (a) What is the entropy change of the system of rod and two reservoirs? (b) What is the total change in entropy of the rod-reservoirs system when 5090 J is conducted through the rod, from one reservoir to the other?
