3 The Principles of Heat, Light, and Sound

4 Heat

5 Heat is transferred three ways… Conduction Convection Radiation

6 The first form of heat transfer is… Conduction

7 Conduction is heat transferred by contact. Source: Maybryonline.org

8 Examples…

9 What stops heat transfer? An Insulator.

10 Examples…

11 The second form of heat transfer is… Convection

12 Hot rises, cold falls creating currents. “Older Than Dirt” WebQuest Think Energy (UK)

13 Examples of convection

14 The third form of heat transfer is… Radiation

15 Radiation is heat as an electromagnetic wave.

16 The wave becomes heat when it hits an object.

17 Examples of radiation
