*    Air Occupies Space

We know that air is everywhere. Thus, every living and nonliving things are rapped up in air. We can better understand it with the example of a balloon. When we start filling air in a flat balloon with our mouth, it increases in size.

That means air has occupied the space inside the balloon, thereby increasing its size.

Similarly, air occupies empty space inside a football, wheels of cycles, cars, etc.

Further, air also occupies space in a room, empty glass, empty bowl, etc.
