Three methods of heat transfer
(Top) heat flows from the hot end to the cool end of the rod. As the distance from the burner flame increases, the temperature of the rod falls by a proportional amount. In a teakettle (bottom left), hot water rises and cold water descends until all the water is at the same temperature. A home heating lamp (bottom right) produces its heating effect by direct transfer of radiant energy.
