Consider a bottle partially filled with water and it is sealed from everywhere so that no air can enter or exit from bottle.Now make a small hole at the bottom of the bottle and hang it vertically so that hole faces downward direction. As we know bottle is sealed from everywhere else so the hole is the only place from where entry or exit of air or water is possible.Now two events will occur one after another repeatedly
- a drop of water came out from hole due to gravity and falls down on ground
- a bubble of air (or air)wil enter in bottle through hole and moves upward against the gravity and mixes with the air present at the top of liquid in bottle.
Now i know the reason for these two events to occur just because to maintain atmospheric pressure of air in bottle and due to gravity.But the thing in which i get confused is that which of the two events will occur first? I tried this experiment myself but not able to figure it out.I personally feel that event1should occur first
