Mr Chua experimented on water movement within a rigid tank. The rigid tank is divided into two equal parts by a partition. Initially, one side of the tank contains 5.0 kg of water at 200 kPa and 25ºC, and the other side is empty. The partition is then removed, and the water expands into the entire tank. The water is allowed to exchange heat with its surroundings until the temperature in the tank returns to the initial value of 25ºC. Determine: a) the volume of the tank. b) the final pressure of the tank

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.
