When water freezes, it:
-
Condenses
No. Condensation happens when water vapor changes from a gas to a liquid. -
Contracts
No. Water does not take up less space when it freezes. -
Expands
Yes! Unlike most substances, water expands to take up more space when it freezes. -
Gains mass.
No. Changing from one state to another does not cause a change in mass.
