What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when particles collide with each other, transferring energy.

Front

What happens to particles as they heat up?

Back

As particles heat up, they gain energy and move faster.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warmer parts of the fluid rise while cooler parts sink.

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves. It does not require a medium, allowing heat to travel through space.

Front

How does the sun warm the sand?

Back

The sun warms the sand through radiation, as heat is transferred from the sun to the sand without direct contact.

Front

What is an example of conduction?

Back

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

Front

What is an example of convection?

Back

An example of convection is boiling water, where hot water rises to the top and cooler water sinks.

Front

What is an example of radiation?

Back

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

Front

What type of heat transfer occurs when you walk on warm sand?

Back

The type of heat transfer that occurs when you walk on warm sand is conduction.

Front

What is the main difference between conduction and convection?

Back

Conduction occurs through direct contact, while convection involves the movement of fluids.
