Heat Transfer: Conduction, Convection, & Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through touching, primarily occurring in solids, especially metals.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases), where warmer areas rise and cooler areas sink.

Front

What is radiation?

Back

Radiation is the transfer of energy in the form of waves or particles through open space.

Front

Which method of heat transfer occurs when you touch a hot object?

Back

Conduction.

Front

What happens to air when it is heated?

Back

Hot air rises, and cold air sinks, creating convection currents.
