We would have often observed how fish or marine life can still live underwater. All living beings need oxygen to survive. The marine life has to absorb the oxygen present in the water. This shows that air contains air ; oxygen for animals to breathe in.
We can heat an empty jar. When we start heating the jar, we observe slight droplets on the jar's glass. This is water vapour out of air.
We have also seen how air needs dust particles for water to settle on up in the skies and atmosphere.
