Answer 1

Answer:

The answer is water.

Explanation:

In liquid state the molecules of water are in random motion and don not have specific arrangement of the molecules. The density of water is around 1 g/ cm3. When the temperature of water is reduced it starts converting into solid state that is ice.

In solid state the molecules of water have specific arrangements and empty spaces are created among the water molecule due to which it expands and it density decreases.
