A pond is covered by a sheet of ice 2.0 cm thick (thermal conductivity 1.6 `jm^(-1)s^(-1)k^(-1)`. The temperature of the lower surface of ice is `0^@ C` and that of the upper surface is `-10^@ C` . At what rate is heat conducted through each square meter of the ice ? What is the direction of this flow of energy ?
