Front

What are the three main types of thermal energy transfer?

Back

Conduction, Convection, and Radiation.

Front

Define conduction.

Back

The transfer of heat through direct contact between materials.

Front

Give an example of conduction.

Back

Touching a hot stove and feeling the heat on your hand.

Front

Define convection.

Back

The transfer of heat through the movement of fluids (liquids and gases).

Front

Give an example of convection.

Back

Warm air rising in a room and cooler air sinking.

Front

Define radiation.

Back

The transfer of heat in the form of electromagnetic waves, such as light.

Front

Give an example of radiation.

Back

Feeling the warmth of the sun on your skin.
