Question

1. Explain with the help of an activity that
air exerts pressure.​

Answer 1

Answer:

When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces.The more particles that hit the walls, the higher the pressure. If a gas is heated up, its particles move around more quickly. ... This increases the pressure

Answer 2

When you pop a blown balloon with a pin, the balloon will move in different directions with a whistling sound. Therefore, we can say that air exerts pressure.
