Question

Liquid have low density then of solid .but ice floats on water . Why

Answer 1

$\huge\underline\purple{Answer:-}$

Solid water, or ice, is less dense than liquid water. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density. Ice's expansion at its freezing point is due to the polar structure of water molecules.

When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding. Solid water, or ice, is less dense than liquid water. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density.

Ice's expansion at its freezing point is due to the polar structure of water molecules. In the liquid phase, water molecules are always in motion and can be packed closely together. As the temperature drops, however, the molecules begin to form hexagonal crystals. The hydrogen bonds created in these crystals arrange the molecules in such a way that more space exists between them than in the liquid phase, resulting in an expansion of around 8.3 percent in volume. Since the water the ice displaces now weighs less than the ice itself, ice is buoyant and floats
