Question

Where does the water we use in our homes come from?

Answer 1

Hint: We have to remember that the molecular formula of water is \[{{\text{H}}_{\text{2}}}{\text{O}}\]. The molecular weight of water is\[{\text{18g}}\]. The water has intermolecular hydrogen bonding between the water molecules. The water can exist in all the states of matter. A solid state of water is called an ice cube. The gas state of water is called water vapour. The liquid state of water is called such water. Hydrogen combines with oxygen in the presence of an electric current to form a product of water. Water is one of the good conductors of electric cities.
\[{\text{2}}{{\text{H}}_{\text{2}}}{\text{ + }}{{\text{O}}_{\text{2}}} \to {\text{2}}{{\text{H}}_{\text{2}}}{\text{O}}\]

Complete answer:
The main source of water is rain only. But we can't store rain directly. Hence, we store rain water in lakes, ponds, wells and borewells. Some natural storage is also available in the world.
According to the above discussion, we conclude that the water we use in our homes comes from rivers, lakes, ponds, wells and some amount of water from groundwater.

Note:
As we know that water is classified as two types. This classification is based on the amounts of minerals. The two types of water are hard water and soft water. The hard water means water contains high amounts of minerals ions. The soft water means water contains low amounts of minerals ions. The hardness of water is divided into two types. There are temporary and permanent hardness of water. This classification of hardness is dependent on the salt contained in the water.
