1200 grams of air is contained in a frictionless piston-cylinder assembly at a pressure of 0.15 MPa and a temperature of 285 K. The air is compressed until the pressure in the cylinder is 0.6 MPa. Since the system is operated diathermal, the temperature in the cylinder is constant. Calculate the work done in the process.
