Why does water expand when it freezes.
Water molecules (H2O) are made of an oxygen atom between two hydrogen atoms. They aren't lined up straight; they're bent at an angle, like a noodle of macaroni. When water freezes into solid ice, these macaroni shapes arrange themselves into hexagons, as shown in [this image](_URL_0_).
The Short Answer
Water molecules (H2O) are made of an oxygen atom between two hydrogen atoms. They aren't lined up straight; they're bent at an angle, like a noodle of macaroni. When water freezes into solid ice, these macaroni shapes arrange themselves into hexagons, as shown in [this image](_URL_0_). The empty space in the middle of each hexagon means that the overall structure takes up more space than if the H2Os just smashed together randomly (i.e. if they were liquid). So the overall volume of water ends up expanding as it freezes into hexagons.
