Content :

 

Air is not only needed for respiration, it is also an important element for several other activities we carry out.

We need air to sail, to fill balloons, to fly aeroplanes, to make fire, to dry things, to pump vehicle tires etc.

Air is a conducting medium for sound: we can hear the sound of speech or noise because of air around us. It happens because air is a good sound conductor. Without air, we will not be able to hear anything and won’t be able to produce any sounds.

Air helps to dry things: (Moisture Balance) When the rain makes the ground to be wet, the air dries it up.

Air helps us to swim in water: When our lungs fill up with air, we can swim higher in the water.

Fire needs air to burn. Air in the tyre helps vehicles to move
