Conduction, Convection, Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when faster-moving particles collide with slower-moving ones, transferring energy.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warm fluid rises while cool fluid sinks, creating a circulation pattern.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium, so it can occur in a vacuum.

Front

Which materials are good conductors of heat?

Back

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

Front

Which material is a poor conductor of heat?

Back

Plastic is a poor conductor of heat and is often used as an insulator.

Front

What happens to warm air in convection?

Back

Warm air rises because it is less dense than cool air, which sinks.

Front

How does heat transfer from a hot pan to your hand?

Back

Heat transfers from the hot pan to your hand through conduction.

Front

What is an example of radiation?

Back

An example of radiation is the heat you feel from the sun or a heat lamp.

Front

What is insulation?

Back

Insulation is a method used to reduce heat transfer, keeping heat in or out of a space.

Front

What is the primary method of heat transfer in liquids?

Back

The primary method of heat transfer in liquids is convection.
