5 moles of monatomic gas undergoes two stages of thermodynamic processes. In the first stage, the gas is compressed from 6.8 L to 3.6 L with a pressure that changes from 2.9 atm to 6.0 atm at a constant temperature of 25.7°C. In the second stage, the pressure of the gas decreased to 1 atm while maintaining a constant volume. (i)     Sketch the PV diagram. (ii)     Determine all thermodynamic processes involved. Write the equations of changes in internal energy ΔU for each process, by using symbols P, V, or Q only. (iii)     Calculate the total work done on the gas during the thermodynamic processes

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.
