P4.6. Steam at 400°C and 10 bar is left in an insulated 10 m^3 cylinder. The cylinder has a small leak, however. Compute the conditions of the steam after the pressure has dropped to 1 bar. What is the change in the specific entropy of the steam in the cylinder? Is this a reversible process? The mass of the cylinder is 600 kg, and its heat capacity is 0.1 cal/g-K. Solve the problem with and without considering the heat capacity of the cylinder. (ANS. (a)~120°C; (b) 360°C)

A well-insulated 0.2kg copper bowl contains 0.10kg of ice, both at −10◦ C. A very hot 0.35kg copper cylinder is dropped into it and the lid quickly closed. The final temperature of the system is 100◦C, with 5g of steam in the container. (a) How much heat was transferred to the water (in all phases); (b) How much to the bowl? (c) What must have been the original temperature of the cylinder? The specific heat of copper is 386 J/kg·K....
