Heat Transfer Review

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another.

Front

What are the three main methods of heat transfer?

Back

Conduction, Convection, and Radiation.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warm fluid rises while cold fluid sinks.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight.

Front

Which method of heat transfer does NOT require a medium?

Back

Radiation does not require a medium; it can occur in a vacuum.

Front

What happens to particles in conduction?

Back

In conduction, particles vibrate and transfer energy to neighboring particles through direct contact.

Front

Can you give an example of conduction?

Back

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

Front

Can you give an example of convection?

Back

An example of convection is boiling water, where hot water rises and cold water sinks.

Front

Can you give an example of radiation?

Back

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