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

Option A

Option B

Option C

Option D

Solution

Liquids have lower density than that of solids. Water is also a liquid so it should also have less density than that of solid that is ice.

But the case is not so and the reason for the same is the cage-like structure of ice. i.e.,

presence of vacant spaces between water $(H_2O)$ molecules when they linked in ice.

The number of these spaces is comparatively less in water. Being more porous than water, ice is lighter than water and floats over the surface of water.
