What is a conductor?

Back

A conductor is a material that allows heat to flow through it easily.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is radiation?

Back

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

Front

How does heat transfer from the sun to the Earth?

Back

Heat transfer from the sun to the Earth occurs through radiation.

Front

What happens to warm air in a room?

Back

Warm air rises because it is less dense than cooler air, demonstrating convection.

Front

What is an example of conduction?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.
