Answer 2

Answer :

• Air exerts pressure, we can prove this by the activity of juice rose in pipe when we suck.

Yes or no :

• Yes, air exerts pressure.

Explanation :

• When we suck air from the straw, less air push on the juice inside the straw than on the juice outside of it, and this imbalance causes more juice to be pushed into the straw whic we are sucking. The juice will rise until the pressure created by the juice column in the straw equals the air pressure difference.
