Question

Pari tied up a polythene bag around two branches of a plant- one had leaves and the other did not. She then kept this plant in her sunlit balcony. She observed both the polythene bags

Answer 1

Air mainly have 4 major components which you have mentioned.

The other components are present in traces and therefore we consider only 4 components for separation of air.

However, the other components will separate in the same way (by fractional distillation) as the 4 above.
