A quantity of a certain perfect gas is compressed from an initial state of 0.083 m3, 1 bar to a final state of 0.034 m3, 3.8 bar. The specific heat at constant volume is 0.726 kJ/kg K, and the specific heat at constant pressure is 1.03 kJ/kg K. The observed temperature rise is 123 K. Calculate the mass of gas present to two decimal places with the SI unit.

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.
