Which statement about air is correct?
Answer and explanation
Correct answer: Air is a mixture of gases, water vapour and particles
Air is a mixture rather than a single pure substance. It contains major gases such as nitrogen and oxygen, smaller amounts of other gases, variable water vapour, and suspended particles such as dust or aerosols. Therefore option D is correct. The other statements are wrong because air is not one gas, it can contain moisture, and dust alone cannot be called air.
