• The transfer of heat through insulation

Which of the following is a good conductor of heat?

• Wood

• Plastic

• Aluminum

• Glass

Explain what happens when you touch a hot frying pan?

• Heat transfers from the pan to your hand through conduction

• The pan absorbs heat from your hand

• Heat transfers from the pan to your hand through radiation

• Heat transfers from the pan to your hand through convection

Why metal is often used in cooking utensils?

• Because metal is a good conductor of heat

• Because metal is a good insulator

• Because metal is cold to the touch

• Because metal is lightweight

What happens to the bread in a grilled cheese sandwich when it is placed on a hot frying pan?

• It cools down due to insulation

• It melts due to convection

• It becomes soft due to radiation

• It becomes golden and toasty due to conduction

Which of the following is an example of conduction?

• Boiling soup in a big pot

• Feeling the warmth of the sun on your skin

• Holding a warm mug of hot cocoa

• Placing a pizza in the oven

How is it possible for you to hold a wooden handle on a hot pan without burning your hand?

• Glass

• Silver

• Iron

Heat transfer through conduction occurs when:

• Heat moves in direct contact in an object

• Heat moves through air

• Heat moves through radiation

• Heat moves through a vacuum
