Front

What is thermal energy transfer?

Back

The movement of heat from one object or substance to another.

Front

What are the three main types of thermal energy transfer?

Back

Conduction, Convection, and Radiation.

Front

Define conduction.

Back

Conduction is 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

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

Give an example of convection.

Back

Warm air rising from a heater and circulating in a room.

Front

Define radiation.

Back

Radiation is the transfer of heat through electromagnetic waves without the need for a medium.

Front

Give an example of radiation.

Back

Feeling the warmth of the sun on your skin.

Front

What happens to warm air in a room?

Back

Warm air rises and cooler air moves in to take its place, creating a convection current.
