One kg of air in a piston-cylinder assembly undergoes two processes in series from an initial state where p1 = 0.5 MPa, T1 = 227oC. Process 1-2: Constant-temperature expansion until the volume is twice the initial volume. Process 2-3: Constant-volume heating until the pressure is again 0.5 MPa. Sketch the two processes in series on a p-v diagram. Assuming ideal gas behavior, determine (a) the pressure at state 2, in MPa, (b) the temperature at state 3, in oC, and for each of the processes (c) the work and heat transfer, each in kJ.
