1. Ammonia (NH₃) is contained in a sealed rigid tank at 0?C, x = 50% and is then heated to 100?C. Find the final state P2, u2 and the specific work and heat transfer.

2. A piston/cylinder system contains 50 L of air at 300?C, 100 kPa, with the piston initially on a set of stops. A total external constant force acts on the piston, so the balancing pressure inside should be 200 kPa. The cylinder is made of 2 kg of steel initially at 1300?C. The system is insulated so that heat transfer occurs only between the steel cylinder and the air. The system comes to equilibrium. Find the final temperature and the work done by the air in the process and plot the process P-V diagram.
