Question

Air is a mixture of gases but it appears to be a single gas

Answer 1

Answer:

'Dont judge a book by its cover'

Air is made up of many gases like hydrogen, oxygen, carbon dioxide, nitrogen etc.

But visually theres nothing, I mean that 'air' is highly transparent, semi fluidish gas which just makes us feel its presence but does not show itslef to us.

Air is just a word to define many different gases combined together forming an atmosphere just like we say water instead of 'Two hydrogen molecules and One oxygen molecule'

Hope you understand.
