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.

Question

A piston-cylinder assembly contains 20 kg of ammonia, initially at 80 kPa and -10°C. The ammonia is compressed to a pressure of 550
kPa. During the process, the pressure and specific volume are related by po¹¹ = constant. Determine the work and the heat transfer,
in kJ.
Determine work
Work can be evaluated:
as equal to the pressure times (final specific volume minus initial specific volume).
O by integrating volume from the initial pressure to the final pressure.
O as equal to the pressure times (initial volume minus final volume).
as the integral of pdV from the initial volume to the final volume.
