A rigid container contains 0.29 kg of hot saturated vapour at an unknown initial pressure P1.  The container is cooled and the temperature drops to 98°C.  It is found that the contents of the container now (at 98°C) are a mixture with quality 0.27.  Calculate the amount of energy that was removed from the container, in KJ.  Neglect kinetic and potential energy changes.  Note that the reported heat transfer must be negative because energy is leaving the container.

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.
