S1 Physics - Heat (Conduction)

What is conduction?

• Transfer of heat through a fluid

• Transfer of heat through direct contact

• Transfer of heat through radiation

• Transfer of heat through evaporation

Which material is a good conductor of heat?

• Wood

• Plastic

• Copper

• Rubber

Which of the following is a poor conductor of heat?

• Metal

• Water

• Air

• Stone

In which scenario does conduction occur?

• Heat traveling through a metal rod

• Warm air rising

• Heat from the Sun warming the Earth

• Warm water evaporating

Which of the following uses conduction to transfer heat?

• A metal spoon heating up in hot soup

• A microwave heating food

• A fan cooling you off

• A radiator warming up a room

Why is a thermos designed with an insulating material?

• To allow heat to flow in

• To prevent heat loss through conduction

• To increase heat transfer

• To block air from entering

How does conduction affect cooking?

• It heats food by moving heat from the stove to the food

• It cools food quickly

• It causes the food to boil

• It melts the food directly

Which of the following is a good conductor of heat in cooking?

• Cast iron skillet

• Plastic spatula

• Wooden spoon

• Paper towel

In what scenario is conduction most effective?

• In a vacuum

• In liquids

• In solids

• In gases

What happens when a hot object touches a cold object?

• Heat flows from cold to hot

• Heat flows from hot to cold

• No heat is transferred

• Both objects remain at the same temperature
