Discussion
A cup of hot coffee is placed on a metal table in a room. By which of the following methods does it lose heat?
Answer: D
It loses heat by conduction, convection and radiation.
Conduction carries heat into the metal table, convection carries it away in rising currents of warm air, and radiation carries it off as infrared. All three act together whenever a hot body sits in air on a solid surface.
