31)  The hydrogen bonds between water molecules become stronger and results the matter to expands below 4°c as the bonds between water molecules are stronger, where they are less likely to break and re-form as they do in the liquid state. As a liquid, water molecules are constantly moving resulting in less expansion. The crystalline arrangement is lease dense than that of the molecules in liquid form which makes the ice less dense than the liquid water. When water freezes, its volume expands.
