Question

Can air be compressed?Mention an activity to justify your answer.

Answer 1

Yes...............you can see a cold drink bottle which shows air pressure while stirring it.

Answer 2

Compressed air is made of the same air you breathe in and out, but that air is compressed into a smaller size and kept under pressure. When you take atmospheric air and then physically force it into a smaller volume, the molecules take up less space and the air is compressed.
