piston–cylinder assembly contains air, initially at 2.6 bar, 134 K, and a volume of 2.6 m3. The air undergoes a process to a state where the pressure is 0.8 bar, during which the pressure–volume relationship is pV = constant. Assuming ideal gas behavior for the air, determine the work for the process in kJ.

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.
