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.
