Inside a piston-cylinder device there is 5 kg of a moist water vapor at 125 kPa. At the beginning there are 2 kg of water in the liquid phase, and the rest is in the vapor phase. Then, heat is transferred to the water; the plunger, which rests on a set of stops, begins to rise when the pressure inside reaches 300 kPa. Heat transfer continues until the total volume increases by 20 percent. a) the start and final temperatures b) the mass of liquid water when the plunger starts to rise c) the work done during this process. Also plot the process on a P-v diagram

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.
