One end of a copper rod is in thermal contact with a hot reservoir at 995 K, and the other end is in thermal contact with a coolerreservoir at 219 K. If 10931 J of energy are transferred from one end to the other, with no change in the temperature distribution,
find the entropy change of the hot reservoir.
Answer in units of J/K
Find the entropy change of cooler reservoir.
Find the total entropy change of the Universe.
