A piston device haves 0.8 kg of an ideal gas initially at 200 kPa and 30oC. The gas is then compressed slowly in a polytropic process during which PV1.3 = constant until the volume is condensed by one-half. Explaine the work done and the heat transfer for this process. [The gas constant of the ideal gas is R=0.2968 kJ/(kg.K) and the specific heat C =0.744 kJ/(kg.K)]
