A piston cylinder assembly contains 32g of oxygen at a pressure of 2.0 atmosphere and a temperature of27^@ CIt undergoes a cycle in which it is first heated at constant volume until the pressure becomes three times, then is expanded isothermally to reduce the pressure to the original value. Finally it is cooled, isobarically back to the original temperature. Calculate the work done and change in internal energy in each process. Represent the process on a P-V diagram.
