Question

How can you show that air exerts pressure ?

Answer 1

When we inflate a very large amount of air in a balloon, the air exerts pressure on the walls of the balloon and ,hence, it bursts.

When we inhale, the air exerts pressure on the walls of our alveoli and they expand.

When we travel into space without an astronaut suit, our veins can burst because of high amount of pressure applied on our veins by the air.

There are many more examples in our daily life also.

Answer 2

As the Question provided here, asked to show that air exerts pressure. Here I'll show it by an example .

$\large \bigstar\sf {\underline{ \underline \color{darkgreen}{example - 1}}} \bigstar$

• Let us take two balloons .

• Now Blow it and also String in it.

• Hang the balloons 8 cm - 10 cm aside on a rim.

• Now , blow air between the balloons.

• ✎This shows that the air exerts pressure.

• ✎ Air exerts pressure on the earth's surface. The pressure exerted by the weight of air of the earth is called Air Pressure.
