Water is heated in a piston/cylinder arrangement at constant pressure. Initially the water is saturated vapor at 200 kPa and has a specific volume of 0.88578 m³/kg. At the final state the temperature of the water is 300 C and has a specific volume of 1.31623 m3/kg. The mass of the water is 2 kg. In the question that follows, select the answer that is closest to the true value. What is the work done by the water in units of kJ ?

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.
