A brass rod is in thermal contact with a constant - temperature reservoir at 128 °C at one end and a constant - temperature reservoir at 37.5 °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 5010 J is conducted through the rod, from one reservoir to the other?
