A piston-cylinder device initially contains 1 kg saturated liquid water at 220°C. Now heat is transferred to the water until the volume expands quadruple of its initial volume. Eventually, the cylinder contains saturated vapor only. (i) Determine the volume at the final stage. Determine the final temperature and pressure. (ii) (iii) Determine the internal energy change of the water. (iv) Sketch the T-v diagram and include all the related information.

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.
