2. When two bodies at different temperatures are placed in thermal contact. how can we extract maximum work from the two bodies? Assuming heal capacities to remain constant, find the change in temperature (Hint: use ontropy relations) and the work obtained. What will be the final temperative if the heat capacities of the two bodies are the same? What is the final temperature if the process was spontaneents? Calculate the temperature for holb cases if the initial temperatures of the bodies are 256K and 144 K respectively. Comment on the reasons for any difference in the two cases.
