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

Consider a piston-cylinder assembly containing 0.1 kg of dry air initially at 300 K and 200 kPa

temperature is 450 K (state 2). Plot the process on P-v and T-v planes and determine the
following quantities: 1W2, 1U2, AH, and 1Q2. Write with proper units.
