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.

Some people think that ice skates slide on ice because ice melts at the pressure exerted by the skating person. Prove by calculation that such a statement is incorrect. Given student with 75kg mass who skates when the air temperature is -3°C. The edge of the ice skate is 28cm long and 3mm wide (the student stands on one leg). For the calculations, consider that the density of water changes from 1.00gcm^-3 to 0.92gcm^-3 while it freezes at 0°C at atmospheric pressure.
