                     •Air is present everywhere around

                     us but we cannot see it. We can only

                     feel its presence. Air also has
                     certain properties.

                     1.      Air occupies space.
                       For example:


                     i) When we blow air in a balloon,

                     blowing air in a balloon increases its

                     size. It is because air occupies
                     space. As we blow more air, balloon

                     grows bigger.
