Paul has different spoons for cooking. He told Sue that he likes to stir hot food with a wooden spoon because it does not burn his hand. Sue disagreed. She said that there was no difference between wooden and metal spoons. Was Sue right? Explain.

• Yes. Metal and wood both conduct heat, and neither spoon will burn Paul’s hand.

• No. Metal is a better conductor than wood, so a metal spoon could burn Paul’s hand.

• No. Metal is a better conductor but the heat energy does not travel to the handle.

• No. Wood is a better conductor than metal and Paul could burn his hand using a wooden spoon also.
