A piston-cylinder assembly contains 1kg of water, initially occupying a volume of 0.25mm^3 at 3 bar. Energy transfer by heat to the water results in a process at constant pressure to a final volume of 0.6058m^3. You may assume that any kinetic and potential energy effects are negligible. Question: (a) Sketch the process on a T-V diagram with all the features clearly labelled (b) Evaluate the work for the process (c) Evaluate the heat transfer

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.
