Question

How is ice less dense than liquid water if density increases on cooling?

I mean ice is a solid and solids are more denser than liquids then why do ice float in water if its a solid?​

Answer 1

Explanation:

This is due to ice's density being less than liquid water's density. Upon freezing, the density of ice decreases by about 9 percent. ... It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.
