A quantity of gas occupies a volume of 0.3m3 at a pressure of 100 MN/m2  and a  temperature of 20oC. The gas is compressed isothermally to a pressure of 500 MN/m2 and then expanded adiabatically to its initial volume. Determine for the quantity of gas : i. The heat received or rejected during the compression ii. The change of internal energy during expansion  iii. The mass of the ga

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.
