What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another due to a temperature difference.

What is an insulator?

Back

A material that reduces the flow of heat.

Front

What is a conductor?

Back

A material that allows heat to flow easily.

Front

What is radiation in terms of heat transfer?

Back

Radiation is the transfer of thermal energy through space in the form of electromagnetic waves.

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

Give an example of conduction.

Back

Touching a hot stove and feeling the heat transfer to your hand.

Front

Give an example of convection.

Back

Warm air rising and cool air sinking in a room, creating a circulation of air.

What is the role of a radiator in heat transfer?

Back

A radiator transfers heat from hot water or steam to the air in a room, primarily through convection.
