Q2. What’s so special about water?

Ans. WATER IS SPECIAL IN MANY WAYS, AND IS ESSENTIAL TO ALL LIVING THINGS.

Water is chemically neutral, yet dissolves many substances, which is why it is so important for life. It is denser as a liquid than a solid and so expand when it freezes. Water is found naturally in all of its three states of matter-solid ice, liquid water and gaseous water vapour. This is unusual, because of the strong bonds between its two hydrogen atoms and one oxygen atom. When cooled, most substances with similar sized atoms to water do not freeze until -30oC (-22oF). Water freezes at a much higher temperature, 0oC (32oF).
