Explanation:
When we blow air into a balloon, it expands because air exerts pressure. Let's understand this concept in detail:
Air has weight:
Air is composed of tiny particles called molecules. These molecules have mass, which means that air has weight. Even though we cannot see the air, it still exists and has weight.
Air occupies space:
Air is not empty space. It occupies space just like any other substance. When we blow air into a balloon, the air molecules take up space inside the balloon.
Air exerts pressure:
Air molecules are constantly moving and colliding with each other and with the walls of the balloon. These collisions create a force known as pressure. When we blow air into a balloon, the air molecules collide with the walls of the balloon and exert pressure on them.
Expanding balloon:
When we blow air into a balloon, the pressure of the air inside the balloon becomes greater than the pressure outside. This causes the balloon to stretch and expand. The elastic material of the balloon allows it to stretch without bursting.
Balancing pressure:
The expanding balloon continues to inflate until the pressure inside the balloon becomes equal to the pressure outside. At this point, the balloon stops expanding because the forces are balanced.
Summary:
In summary, when we blow air into a balloon, it expands because air molecules have weight, occupy space, and exert pressure. The pressure of the air inside the balloon is greater than the pressure outside, causing the balloon to stretch and expand.
