1. Transfer of Thermal Energy

2. What are the three ways heat can move?
Conduction
Convection
Radiation

4. 1.Conduction: heat is transferred from one
object to another by direct contact.

5. Conduction
The transfer of thermal energy through direct contact between particles of matter.

6. 2.Convection: heat is transferred by the movement of currents within a fluid (liquid or gas).

7. Convection
Heat is transferred by the movement of currents within a liquid or gas.

8. 3.Radiation: the transfer of energy by
waves. Radiation is heat transferred
without touching.

9. Radiation
The transfer of energy (heat) by electromagnetic waves. It does not require matter to transfer its heat.

10. 4. Conductor: a material that allows
transfer of energy.
5. Insulator: a material that slows the

11. LETS PRACTICE!!

12. In the above diagram how does the water become heated?
conduction
(B) convection
(C) radiation

13. In the above diagram what happens to the heated water from the bottom of the pot?
(A)  Heated liquid rises to the top then loses heat energy & drops
(B) Heated liquid drops to the bottom loses heat energy then rises to the top

14. This is an example of?
Conduction
Radiation
Convection
