Unformatted text preview: at the temperature of T 1 and T 2 ( T 1 > T 2 ). Imagine an ideal engine working between the two bodies. (a) What is the ²nal equilibrium temperature of the system? (b) What is the ²nal equilibrium temperature if the engine is reversible? (c) What is the maximum work that we can extract from such a system? (d) Imagine now that the system at high temperature can be considered a reservoir of heat. The cold source, however, is not a very good cooling system and therefore it becomes warmer as heat ³ows into it (its heat capacity is again C 2 ). If the hot source is initially at T 1 = 100 o C and the cold source is water at T 2 = 0 o C , calculate the maximum work that can be extracted from this system (the speci²c heat of water is c = 1 cal/gK , and we have 10 6 g of cooling water at our disposal). 1...
