Air contained within a piston-cylinder assembly undergoes three process in series: Compression at constant pressure from p1=70 kPa, V1 = 0.22 m³ to state 2. Constant volume heating to state

3, where from p3=350 kPa. Expansion to initial state, during which the pressure-volume relationship ispV12 = constant. ) Find the volume at state 2, ii) Find the work for each process, and O Sketch the p-V diagram of the processes (cycle).
