1. The boiling temperature of water is 100 °C. If you put boiling water in a mug placed at the table top, you observed that after some time the water cools down, decreasing the temperature of water in the mug. Why is this so? Explaín using the Zeroth Law of Thermodynamics.

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.
