A closed, rigid container is filled with 1.5 kg water at 100 kPa, 55◦C, 1 kg of stainless steel and 0.5 kg of polyvinyl chloride, both at 20◦Cand 0.1 kg of hot air at 400 K, 100 kPa. It is now left alone, with no external heat transfer, and no water vaporizes. Find the final temperature and the entropy generation for the process.
