A piston-cylinder device whose piston is resting on a set of stops initially contains 3kg of air at 2bar and 27°C. The mass of the piston is such that a pressure of 4bar 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).

Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.
