Question

Explain why, when an empty glass bottle is inverted into a bucket of water vertically, what does not enter the bottle.​

Answer 1

When an empty glass bottle is inverted into a vessel, containing water, the water doesn't enter the glass bottle because of the air present in bottle. The air occupies space and thus the water can only enter if the air is given a way to get out of the bottle ( this can be done by slightly tilting the bottle)
