Question

When an empty glass is inverted into a bucket containing water, water does not enter into the glass? Why

Answer 1

As air occupies the empty space, it will hinder the entry of water into the glass.

Once the glass gets a way to come out of the glass, it will get water filled inside it.

The air in the glass does not allow the water to fill the glass.

But if you compress the air little bit then you can easily place the glass way down into the water.
