Question

liquids generally have lower density as compared to solids.But you must have observed that ice floats on water. find out why.

Answer 1

When water turns into ice it forms a cage like structure which is why the volume increases.

We know that density =mass/volume
So more the volume less is the density.
Hence the density decreases and ice floats on water.
Hope that helps you :-)

Answer 2

Liquid has low density than solids but the ice floats on water because it has small pores present in the ice which helps them to float in water
