A piston-cylinder device initially contains steam at 5 MPa and 450°C. Now, steam loses heat to the surroundings and the piston moves down hitting a set of stops at which point the cylinder contains saturated vapor water. The cooling continues until the cylinder contains water at 180°C. Show the process on a T-v diagram with respect to saturation lines showing the three states it passes through. Also, put the values of temperature, pressure and specific volume for each state on the figure.

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.
