GENERAL HISTOLOGY

Detailed explanation-1: -The density of water is maximum at 4∘C, the density of the ice is less than the water because of its weak intermolecular force of attraction. As the density of water is more, it is heavier than ice. Hence ice floats on the surface of the water.

Detailed explanation-2: -Ice floats on water because it is less dense than water. When water freezes into its solid form, its molecules are able to form more stable hydrogen bonds locking them into positions. Because the molecules are not moving, they’re not able to form as many hydrogen bonds with other water molecules.

Detailed explanation-3: -Because frozen water is less dense than liquid water, the frozen water will not sink. Water’s triangular molecule shape, combined with it’s lower density allow it to float. Compared to liquid water, ice has a lower density and a bigger volume. That is, it is lighter and bigger than the same amount of liquid water.
