What acts as condensation nuclei in the atmosphere?
Answer and explanation
Correct answer: Dust and salt particles
Condensation nuclei are tiny particles on which water vapour can begin to condense when air cools to a suitable temperature. Dust and salt particles provide these surfaces and help microscopic water droplets or ice crystals form, leading to clouds. Hence option D is correct. Oxygen, nitrogen and argon are atmospheric gases, but they do not normally provide the solid surfaces required for this nucleation process.
