Radiation transfers heat through:

• The movement of liquids and gases

• The direct contact between objects

• Invisible waves that travel through space

• The trapping of heat inside materials

Which of these real-world examples best demonstrates conduction?

• A metal pot heating up on a stove burner

• The Sun warming a sandy beach

• Steam rising from a hot bowl of soup

• A fan pushing warm air through a room

Why do metal objects feel colder than wooden objects at the same temperature?

• Metal absorbs less heat than wood

• Metal is a better conductor, so it transfers heat away from your skin faster

• Wood produces its own heat

• Metal traps heat better than wood
