Radiation, convection, conduction

Front

What is convection?

Back

Convection is the primary way heat travels through liquids and gases.

Front

What is radiation?

Back

Radiation is the transfer of energy by waves or particles.

Front

Which materials are good conductors of heat?

Back

Good conductors of heat include metals like copper, iron, and aluminum.

Front

What is an insulator?

Back

An insulator is a material that reduces the flow of heat.

Front

How does heat move?

Back

Heat moves from warm places to cooler places.

Front

What is conduction?

Back

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

Front

Give an example of convection in everyday life.

Back

An example of convection is the way warm air rises and cool air sinks in a room.

Front

What is a good example of radiation?

Back

An example of radiation is feeling the warmth of the sun on your skin.

Front

What is the difference between a conductor and an insulator?

Back

A conductor allows heat to flow easily, while an insulator resists heat flow.

Front

What happens to particles in a liquid when heated?

Back

When heated, particles in a liquid move faster and spread apart, causing convection currents.
