Two Objects With Identical Heat Capacities C Are Used As The Heat Reservoirs To Drive A Heat Engine The Hot Object Is I 1 (54.51 KiB) Viewed 67 times

Two objects with identical heat capacities C are used as the heat reservoirs to drive a heat engine. The hot object is initially at temperature Ty and the cold object is initially at temperature Tc, but as heat gradually leaves the hot object its temperature decreases, and as heat enters the cold object its temperature increases. When the temperatures equalize, at some temperature Tr, the engine stops. Then a) What is the change in entropy of the hot object, as a function of C, TH, Tp? What is the change in entropy of the cold object, as a function of C, Tc, Tp? b) What limit does the 2nd Law impose on Tp? Find T; if Asuniverse = 0, and find the work done by the engine in that case.
