Answer:

That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer. In a barometer, a column of mercury in a glass tube rises or falls as the weight of the atmosphere changes.

Answer: Take a tin-can having airtight cap (screw cap). Remove the cap and boil some water in it, so that steam comes out and in this way air from inside goes out.

As the tin can crumbles, we know that air has pressure.
