A pistoncylinder device contains 0.15 kg of carbon monoxide initially at 2MPa and 350C. The carbon monoxide is first compressed isometrically to 500kPa, then it is expanded isothermally to the initial pressure and finally compressed isobarically back to the initial state. Determine the boundary work for each process and the net-work of the cycle. Draw the PV diagram of this process labeling states 1, 2 and 3.
