Question

Explain why when an empty glass of bottle is inverted into a bucket of water vertically water does not enter the bottle?

Answer 1

Hi buddy,

           When an empty glass is inverted vertically into the bucket, the air filled inside the glass doesn't allow water to come inside the glass. But, when we rotate it a bit ( such as at 45° angle) the air escapes from the glass as air has less density than that of water. Hence, now water gets capable to be filled inside the glass.

Answer 2

Answer:

When the bottle was tilted, the air was able to come out in the form of bubbles, and water filled up the empty space that the air has occupied. This activity shows that air occupies space. It fills all the space in the bottle. It is present everywhere around us.
