Thermal Energy Quiz

Heat transfer always goes from-

• Cold to Hot
• Hot to Cold
• Heat doesn't transfer
• Freezing to Cold

What happens to particles as they heat up?

• They slow down
• Nothing
• They don't move
• They speed up

What type of material makes the best insulators?

• Aluminum
• Copper
• Styrofoam
• Metal

Hot objects begin to cool as-

• cooler air is transferred to the hot object.
• thermal energy in the object is transferred to the surrounding air.
• atoms in the object react with the oxygen in the air.
• thermal energy in the object cancels out energy in the air

Which sentence explains why a cold metal spoon placed in a pot of boiling water becomes hot?

• Thermal energy is transferred from the spoon to the water.
• Thermal energy is transferred from the water to the spoon.
• Thermal energy in the water is transformed into kinetic energy in the spoon.
• Thermal energy in the spoon is transformed into kinetic energy in the water.
