A vertical piston- cylinder assembly contains 0.6 kg of air (K=1.4, R= 287J/Kg.K) initially at 110 KPa and 27 C (state 1). The air is first compressed isentropic ally to a temperature of 117 C ( state 2) which is followed by a constant pressure expansion process that leads to a final volume ( state 3) that is identical to the initial volume. Calculate
A) The volumes corresponding to all three states
B) The temperature and pressure of air in its final state
C) The total boundary work corresponding to the entire process ( state 1 - state 3)
