closed rigid container

1. A closed rigid container is filled with 3 lbm water at 1 atm, 130 F, 2 lbm of stainless steel and 1 lbm of polyvinyl chloride, both at 70 F, and 0.2 lbm of air at 700 R, 1 atm. It is now left alone with no external heat transfer, and no water vaporizes. Find the final temperature and air pressure.

2. An engine, shown in Fig. P3.126, consists of a 200-lbm cast iron block with a 40-lbm aluminum head, 40 lbm of steel parts, 10 lbm of engine oil, and 12 lbm of glycerine (antifreeze). Everything has an initial temperature of 40 F, and as the engine starts it absorbs a net of 7000 Btu before it reaches a steady uniform temperature. How hot does it become?
