Conduction, Convection, Radiation Level 1

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

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 heat in the form of rays, waves, or particles, and does not require a medium to travel.

Front

Give an example of conduction.

Back

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

Front

Give an example of convection.

Back

An example of convection is when you boil water and see the hot water rising and cooler water sinking.

Front

Give an example of radiation.

Back

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

Front

What happens to warm air in a room?

Back

Warm air rises because it is less dense than cooler air.

Front

How does a hair dryer work?

Back

A hair dryer uses convection to blow warm air onto wet hair, helping it to dry.

Front

What is the role of heat lamps for baby chickens?

Back

Heat lamps provide radiation to keep baby chickens warm.

Front

What causes sunburn?

Back

Sunburn is caused by radiation from the sun damaging the skin.
