There are two systems containing the same substance under different conditions. The first is a frictionless piston-cylinder device, and the second is a rigid container. They both contain 10 kg of an ideal gas, each at the same temperature, pressure, and volume. It is desired to raise the temperatures of both systems by 20 °C. Determine the amount of additional heat, compared to the rigid container, that must be supplied to the gas in the cylinder, held at constant pressure, to achieve this result. Assume that the molar mass of the gas is 25

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.
