Front

How does heat transfer occur in a campfire?

Back

Heat is transferred to people around the fire primarily through radiation.

Front

Why is brick a better material for a fireplace than metal?

Back

Brick is heat resistant, meaning it can withstand high temperatures without conducting heat away quickly.

Front

What happens to a rock in the sun during the day?

Back

It absorbs heat through radiation, causing it to become hot.

Front

What is an example of conduction in everyday life?

Back

Grabbing a hot pot handle, where heat is transferred from the pot to your hand.
