Dorien says that when water molecules freeze, they stop moving. Is he correct? Why?
What is Dorien is not correct because the ice molecules are still moving, just very slowly (vibrating).

Kenyah says that if you took all of the atoms out of a pencil, then there would just be lead left. Is she right? Why?
What is Kenyah isn’t correct. Atoms make up all matter. If you took the atoms out of a pencil, then there wouldn’t be anything left.

Two metals look the same. Would mass and volume be useful in determining whether the metals are the same substance? Explain.
What is no, mass and volume would not be useful because they are not properties. The metals could have different mass and volume but still be the same metal, and they could have the same mass and volume and be different metals.
