Robert Matthew Van Winkle takes 1 kg of ice and dumps it into 1 kg of water and, when equilibrium is reached, he has 2 kg of ice. The water was originally at 0°C. What was the original temperature of the ice? For water, specific heat capacity = c = 1 kcal/kg-C°. For water, latent heat of fusion = 80 kcal/kg-C°. For ice, specific heat capacity = c = 0.5 kcal/kg-°C

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.
