The Principles of Heat, Light, and Sound

Heat

Heat is transferred three ways… Conduction Convection Radiation

The first form of heat transfer is… Conduction

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

Examples…

What stops heat transfer? An Insulator.

Examples…

The second form of heat transfer is… Convection

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

Examples of convection

The third form of heat transfer is… Radiation

Radiation is heat as an electromagnetic wave.

The wave becomes heat when it hits an object.

Examples of radiation
