Solve the below problem:
Q: A piston/cylinder contains 2 kg of air at 27°C, 200 kPa, shown in Fig. The piston is loaded with a linear spring, mass and the atmosphere. Stops are mounted so that V stop= 3 m3, at which point P = 600 kPa is required to balance the piston forces. The air is now heated to a final pressure of 400 kPa. Find the final temperature, volume and the work and heat transfer. Find the work done on the spring.
