A vertical piston-cylinder assembly contains 0.3 kg of air( k=1.4, R=287 J/kg*K) initially at 155 kPa and 27 degree C. The is compressed isentropicallu to a temperature of 136 degree C. Followed by a constant pressure expansion process that leads to a final volume that is identical to the initial volume. Find:

I) The volumes corresponding to all three states

II) The temperature and pressure of air in its final state

III) The total boundary work corresponding to the entire process.
