A piston-cylinder device contains 3 Ibm of refrigerant R-134a at 30 psia and 5°F. It is now heated to 65 psia and 60°F in a process where the pressure variation with volume follows: = C, dv where Cis a constant.

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.
