Hi
How can you prove that empty bottle contain air?
To show that air is present everywhere we will perform the following experiment -:
Take an empty glass bottle. Now, hold the bottle in an inverted position into the bucket filled with water (with its open mouth facing downwards). Water will not move inside the bottle because the bottle is filled with water and there is no space for air to escape. Now, tilt the bottle in water. Air present in the bottle comes out in the form of bubbles. As the air from the bottle escapes, water starts entering into the bottle and occupies the place of air. This activity shows that air occupies space and is present everywhere.
