Problem
1. A constant pressure container is filled with 1 kg of stainless steel and 0.5 kg of PVC (polyvinyl chloride) both at 20oC and 0.25 kg of hot air at 500 K, 100 kPa. The container is now left alone with no external heat transfer.
a. Find the final temperature.
b. Find the process work.
2. A spring-loaded piston/cylinder contains 1.5 kg of air at 27oC and 160 kPa. It is now heated to 900 K in a process wherein the pressure is linear in volume to a final volume of twice the initial volume. Plot the process in a P-v diagram and find the work and heat transfer.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
