Two finite, identical, solid bodies of constant total heat capacity per body, Cp, are used as heat sources to drive a heat engine. Their initial temperatures are T1 and T2. The reservoirs remain at constant pressure and do not change phase. Finally afterwards, because of the work done by the heat engine, the two reservoirs arrive at a common temperature Tf . First, find the nal temperature Tf (hint, use the second law to find it). Find the maximum work obtainable from the system.

Consider two bodies with temperature independent heat capacities C1 and C2, and initial temperatures T1 > T2. (a) If the two bodies are brought into contact such that the only heat exchange is between them, what is the final temperature Tfinal , and what is the change in entropy. (b) Suppose instead that the difference in temperature between the two bodies is used to drive an ideal heat engine (Carnot cycle). In one operation of the cycle some amount of...

Two solid bodies of equal mass and identical composition, isolated from the surroundings and each other and kept initially at temperature T1 and T2 are brought into thermal contact until they attain thermal equilibrium with each other. Compute the amount of entropy change of the universe in terms of T1, T2, and the heat capacity C_p of each body , assuming the process to take place at constant pressure exerted on them by the environment and show that the entropy...
