Air is the earth's atmosphere..its a mixture of several gases and other elements..it is that clear gas where living beings breathe..it has mass and weight as it is a form of matter..it creates atmospheric pressure..to prove that it has weight..take a balance to measure weights...just take a scale for this experiment and a holder to hold it..then two balloons and fill air of same quantity and amount..tie both the ends at the top parts of the balance and observe..you will see any one of them will lose air from it faster..and the other balloon with required amount of air in it will hung towards its side..this shows and proves it has weight..Happy to Help :)
