Question: A piston-cylinder device whose piston is resting on a set of stops initially contains 3kg ofair at 2bar and 27C. The mass of the piston

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