Answer:

this happens when it freezes

Explanation:

When water freezes, its molecules get arranged in a crystalline structure, thereby attaining a defined shape. This crystalline structure is less dense, and since there are gaps between individual molecules in the structure, the overall volume increases and water expands

Answer:

Water expands as it freezes because water molecules are very loosely bound. They are arranged in a hexagonal pattern inside of the ice. As the temperature lowers, the molecules move slower, which causes them to get closer together.
