Question

Liquids have lower density than solids. But ice floats on water. Why?

Answer 1

Answer:

Liquids generally have lower density as compared to solids but ice floats on water. ... These spaces are larger as compared to spaces in water molecules. Thus the volume of ice is greater than water. Hence the density of ice is less than of water.

Answer 2

Answer:

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.
