Question

Liquids generally have lower density as compared to the solids but u must have observed that ice float on water. Why?

Answer 1

Though ice is solid but it floats on water.

This is Because is ice have LOWER​ DENISTY than water.

Answer 2

Hi there !!

We know that :

Density = Mass / Volume

As volume increases , density decreases.
Also as volume decreases , density increases

Here in this case , volume of ice increases as it freezes to form a solid.But mass is the same in both the cases.

The volume is increased due to the creation of empty spaces , when water is freezes to form ice.

As volume of ice is more , its density is less.

As the density of water is more than ice , ice floats on the surface of water
