Question

The density of water less than ice why ice float in water

Answer 1

That makes the ice foot in water. its because the chemical bonds between the H2O molecules are forced into being longer, expanding the water and forming a crystal (ice). When something at constant mass increases in volume, it's densitydecreases. Thus, ice is less dense than water , causing it to float.

Answer 2

As density of water is more . Therefore, the buoyant force acted on the the ice is more. So, it floats.
