A piston-cylinder device contains 2.2 kg of nitrogen initially at 100 kPa and 25°C. The nitrogen is now compressed slowly in a polytropic process during which PV3 = constant until the volume is reduced by one-half. Determine the work done and the heat transfer for this process, in kJ. Use R= 0.2968 kJ/kg.K and C,= 0.744 kJ/kg.K
