5-38 A piston-cylinder device contains 0.8 kg of nitrogen initially at 100 kPa and 27°C. The nitrogen is now compressed slowly in a polytropic process during which PV1.3 = constant until the volume is reduced by one-half. Determine the work done and the heat transfer for this process. and Tz [R & Ç given case 4: • Polytropic (PV" constant) n P2 = V2 T2 (( *:)** (*) 。 Pi Wb = m R (T2 -T.) 1-n
