Question:

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

Answer:

When water freezes to form ice, some empty spaces are created. As a result, volume increased for the same mass of water. In some words, mass per unit, volume or density of ice is lower than that of water and hence ice floats on water. (The density of water is maximum at 4.C.)
