Answer 1

Answer:

There are various examples that can prove that air exerts pressure, and few of them are: Water glass trick: fill a glass with one third water and place a cardboard to cover up the entire mouth of the bottle or glass. ... The air pressure will hold the cardboard for at least 15 seconds automatically.

Fountain Bottle. Fill a 2-liter soda bottle half full of water. Take a long straw and insert it in the mouth. Wrap a lump of clay around the straw to form a seal. Blow hard into the straw—then stand back. Your blowing increases the air pressure inside the sealed bottle. This higher pressure pushes on the water and forces it up and out the straw.
