When molecules in a substance vibrate faster and faster, what happens to the temperature of the substance?

• It stays the same.

• It gets warmer.

• It gets colder.

• It depends on the change in speed of the vibrations.

Can heat be created or destroyed?

• Yes
• No
• Only when things are cooling off
• Only when things are warming up

When things are cold molecules are moving...

• Fast
• Slow
• They are not moving
• They are moving by not fast or slow

What is the definition of CONDUCTION?

• When heat is transferred from objects like rays of light or electromagnetically.
• a  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.
• When heat transfers from objects that are touching.
• When heat transfers through the heater or AC in your house.
