In the picture: an illustration of the arrangement of water molecules at temperatures around the freezing point, arranged around a single reference molecule. The white area shows the orderly and directional organization of the water density in the form of an "oyster", which results from the properties of the bonds between the hydrogen molecules. The orange color shows a "volume increase area", which a water molecule cannot penetrate, due to its structural characteristics. Source: IBM.
