Conduction, Convection, Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when heat moves from a warmer object to a cooler one through physical touch.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer parts of a fluid rise and cooler parts sink, 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 to travel through, meaning it can occur in a vacuum.

Front

Example of conduction in everyday life?

Back

An example of conduction is when you touch a hot stove and feel the heat transfer to your hand.

Front

Example of convection in cooking?

Back

An example of convection is when you boil water in a pot; the hot water rises to the top while cooler water sinks.

Front

Example of radiation from the sun?

Back

The heat you feel from sunlight is an example of radiation, as it travels through space to warm you.

Front

How does a heat lamp warm baby chickens?

Back

A heat lamp warms baby chickens through radiation, as the heat is emitted from the lamp and warms the chicks without direct contact.

Front

What happens when you get sunburned?

Back

You get sunburned due to radiation from the sun, which can damage your skin cells.

Front

What is an example of convection in nature?

Back

An example of convection in nature is the wind, which is caused by the uneven heating of the Earth's surface.

Front

What is the best example of conduction?

Back

The best example of conduction is an egg cooking in a frying pan, where heat is transferred directly from the pan to the egg.
