1 METHODS OF HEAT TRANSFER

2 CONVECTION Convection is the transfer of heat by the actual movement of the warmed matter. Convection is the transfer of heat energy in a gas or liquid by movement of currents.

3 CONVECTION Hot water rises, cools, and falls
Heated air rises, cools, then falls Air near heater is replaced by cooler air, and the cycle repeats

4 CONVECTION

5 SEA BREEZE AND LAND BREEZE

6 CONDUCTION Conduction is the transfer of energy through matter from particle to particle. It is the transfer and distribution of heat energy from atom to atom within a substance.

7 HOW DOES CONDUCTION HAPPEN?

8 RADIATION Sunlight is a form of radiation that is radiated through space to our planet without the aid of fluids or solids. Since there are no fluids in space, convection is not responsible for transferring the heat. Thus, radiation brings heat to our planet.

Conduction, Convection, Radiation
Radiation – the transfer of energy through space. Heat transfer by radiation takes place with no direct contact between a heat source and an object. Example.
