You are planning to go for a hike on a hot day , so you put your bottle of water in the freezer. when you take it out, you see that the bottle has expanded . explain why this happened . your explanation should include the hydrogen bonding of water and how it affects the density of the water.

When the water freezes the density of water molecules and hydrogen bonds expanded b/w the molecules and the freezes water molecules shaped into six-cubic structure which is compact shaped structure

Explanation:

when the water molecules freezes the density increases and molecules expands due to which space creates b/w hydrogen bonds of the  molecules . the density of the freezes molecules of water becomes 3.98 centigrade and
