What is conduction?

Back

Conduction is the transfer of heat through direct contact, such as when ironing a shirt.

Give an example of conduction.

Back

An example of conduction is touching a hot stove.

Front

What is an example of convection in everyday life?

Back

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

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through the movement of fluids.

Front

What is an example of radiation?

Back

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