Air is compressed adiabatically from p1 = 100 kPa, T1 = 300 K to p2 = 1500 kPa, v2 = 0.1227 m3 /kg. The air is then cooled at constant volume to T3 = 300 K. Assuming ideal gas behavior and neglecting kinetic and potential energies, calculate the work for the first process and the heat transfer for the second process, each in kJ per kg of air.
