Please show all the work.
A piston-cylinder device whose piston is resting on a set of stops initially contains 3 kg of air at 2 bar and 27 degree Centigrades. The mass of the piston is such that a pressure of 4 bar is required to move it. Heat is now transferred to the air until the volume doubles. Determine the work done by the air and the total heat transferred to the air during the processes. Sketch the processes on a P-V diagram. (Do not assume constant specific heats).
