Question

Why ice floats in water?

Answer 1

As it cools further and freezes into ice, it actually becomes less dense. On the other hand, most substances are most dense in their solid (frozen) state than in their liquid state. Water is different because of hydrogen bonding. ... The heavier water displaces the lighter ice, so ice floats to the top.

Answer 2

1.As Ice is less dense than water it floats on water.

2.Usually all substances, their solid state is more dense than the liquid state.But in the case of water its not.

3.Solid water, or ice, is less dense than liquid water.

Ice is less dense than water because of its open crystalline structure, which lowers the density.
