Question
Which of the following statement is correct?
Answer: Option A
:
A
Air occupies space and has mass, therefore, it is matter. Air can be compressed and it exerts pressure in all the directions. For example, when we inflate a balloon, air occupies the space in the balloon and exerts pressure on the walls of the balloon. Air around us is a mixture of gases. It contains nitrogen, oxygen, argon, other gases and also water vapour.
