1. Heat Transfer

2. Thermodynamics - The study of how heat moves
Heat will transfer until both objects are in THERMAL EQUILIBRIUM
This means they are both the SAME TEMPERATURE.

3. Heat Transfer Heat can be transferred in 3 ways
Conduction
Convection
Radiation
Heat flow depends on the temperature difference – flows from hot to cold

4. Heat Conduction
Conduction – is the transfer of heat through materials by the direct contact of matter

5. Heat Conduction

6. Heat Conduction
When you heat a metal strip at one end, the heat travels to the other end. As you heat the metal, the particles vibrate, these vibrations make the adjacent particles vibrate, and so on and so on, the vibrations are passed along the metal and so is the heat.

7. Heat Convection
Convection – is the transfer of heat by the motion of fluids (liquids and gases)

8. Heat Convection

9. Convection Currents

11. Convection Currents

12. Convection Currents
Much of Earth’s climate is regulated by giant convection currents in the ocean

13. Heat Radiation
Radiation – is the transfer of heat by electromagnetic waves – no medium
