A box shaped close system with a movable top contain water as working as fluid was kept a temperature of 293 K. The pressure inside at this state was 100 kPa. Weights are placed on the movable top to maintain a constant pressure on the water. Later the box was supplied heat energy so that the temperature inside reached to 673 K. How much work does the working fluid inside did on the movable top?

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.
