Conduction, Convection and Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight, which can travel through a vacuum.

Front

How does heat transfer occur in conduction?

Back

In conduction, heat is transferred when particles in a hotter object collide with particles in a cooler object, transferring energy.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a hot soup.

Front

What is an example of convection?

Back

An example of convection is warm air rising and cool air sinking in a room, creating a circulation of air.

Front

What is an example of radiation?

Back

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

Front

In which states of matter does convection occur?

Back

Convection occurs primarily in liquids and gases.

Front

What direction does heat flow in conduction?

Back

In conduction, heat flows from the hotter substance to the colder substance.

Front

What is the primary way heat travels through liquids and gases?

Back

The primary way heat travels through liquids and gases is convection.
