A mass of 6.7 kg of steam is contained within a piston-cylinder assembly. The steam undergoes an expansion from its initial state with e1 = 2617.6 kJ/kg to its final state with e2 = 2506.2 kJ/kg. During the process there is a heat transfer of 72 kJ to the steam. Also, a paddle wheel does 33 kJ of work on the steam. Calculate the amount of work (kJ) done by the steam on the piston during the process. Please show all work

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.
