2 The Principles of Heat, Light, and Sound

3 Heat

4 Heat is transferred three ways…
Conduction Convection Radiation

5 The first form of heat transfer is…
Conduction

6 Conduction is heat transferred by contact.

7 Examples…

8 What stops heat transfer?
An Insulator.

9 Examples…

10 The second form of heat transfer is…
Convection

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

12 Examples of convection

13 The third form of heat transfer is…
Radiation

14 Radiation is heat as an electromagnetic wave.

15 The wave becomes heat when it hits an object.

16 Examples of radiation

17 Quick Review!

18 Heat Transfer Review

19 1. Heat is transferred through direct contact.
