Question

How will you show that an empty glass bottle is filled with air​

Answer 1

Answer:

The air present in the empty glass bottle prevents the water from entering it. We conclude that air occupies space. If we tilt the bottle held in water, we will find that the air present in thebottle goes out in the form of airbubbles. ... A glass bottle which appears to be empty to us is actuallyfilled with air.
