liquid water each water molecule is bonded On average to 3 other water molecules. The Averagae distance between them is 1.82 Angstroms In solid water , each water molecule is bonded to 4 other water molecules and the bonds are farther apart (2.76 A) Density For the same amount (mass) of water molecules, the volume occupied is greater for solid water compared to liquid water. Therefore, the density of solid water is less than the density of liquid water. M
