A well-insulated tank fitted with an electrical resistor of negligible mass holds 1.5 kg of nitrogen (N2 ), initially at 30 °C, 0.2 MPa. Over a period of 20 minutes, electricity is provided to the resistor at a constant voltage of 120 V and with a constant current of 1 ampere. Assuming ideal gas behavior and constant specific heats, determine the nitrogen’s final temperature (in K), and the final pressure (in bar

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.
