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

5.10. (a) Show that the heat transferred during an infinitesimal quasi-static process of an
ideal gas can be written
Cv vdP + CP PdV.
nR
nR
Applying this equation to an adiabatic process, show that PV' = const.
(b) An ideal gas of volume 0.05 ft³ and pressure 120 lb/in² undergoes a quasi-static
adiabatic expansion until the pressure drops to 15 lb/in². Assuming y to remain
constant at the value 1.4, calculate the final volume. Calculate the work.
