HEAT TRANSFER THROUGH CONVECTION. Like conduction and unlike radiation, convection requires a medium. However, in conduction the heat is transferred from one molecule to another, whereas in convection the heated fluid itself is actually moving. As it does, it removes or displaces cold air in its path.
The other way in which energy is transferred is as heat. Heat is the energy transferred from a hotter object to a colder one. A combustion reaction, such as that in Figure 5.1(b), releases the chemical energy stored in the molecules of the fuel in the form of heat.
