Question

air exerts pressure give reason​

Answer 1

Answer:

Air is made up of molecules of different gases. The molecules are colliding with each other continuously with the walls of the container. 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.

Answer 2

• The molecules of various gases make up the air we breathe.
• The molecules are constantly clashing against the container's walls.
• When a molecule collides with a wall, a tiny force is applied to the wall.
• The total of all these impact forces creates the pressure produced by the gas.

• Some steam in the can condenses into water when water is poured over it, lowering the quantity of air within.
• The pressure of air within the can lowers as compared to the pressure of air outside the can.
• As a result, the can is squeezed.
• This action proves that air exerts pressure once more.
