A piston/cylinder system contains 50 L 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 a balancing pressure inside should be 200 kPa. The cylinder is made of 2 kg steel initially at 1300?C. The system is insulated, so heat transfer occurs only between the steel cylinder and the air. The system comes to equilibrium. Find the final temperature and the entropy generation.
