Question

show the experiment that air excert pressure

Answer 1

Take a water bottle. Make holes on the water bottle. Then take M seal and close that holes. now pour water in it and then slowly slowly take out M seal from all holes. Now u will observe that water comes out. But one more thing you will observe that the lowermost hole displaces water more farther than the upper holes. This is due to the reason that air puts pressure on water from upside.Now put cap on the bottle and do same exleriment again u will find that water does not go much far becoz, air does not exert pressure on water.
