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 hotter 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 everyday life?

Back

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

Front

Example of radiation in everyday life?

Back

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

Front

How does a heat lamp warm baby chickens?

Back

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

Front

What happens to a rock in the sun?

Back

A rock in the sun gets hot due to radiation, as it absorbs heat from the sunlight.

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 insulation in heat transfer?

Back

Insulation reduces heat transfer by conduction, convection, and radiation, keeping heat in or out of a space.
