Review Matter-2

When water freezes into ice, its volume increases. What happens to its mass?

  1. It increases.

    No. When water freezes, it takes up more space, but the mass stays the same.
  2. It stays the same.

    Yes. When water freezes, it expands to take up more space, but its mass stays the same. Mass is the measure of how much "stuff" is there. Freezing water does not create new water or add more "stuff". It just makes the water take up more space.
  3. It decreases.

    No. The mass stays the same, even when the water freezes.
  4. Water does not have mass.

    No. Everything that is made out of matter has mass.
