What can provide condensation nuclei for cloud droplets?
Answer and explanation
Correct answer: Dust particles
Dust particles can act as condensation nuclei because water vapour can collect and condense on their tiny solid surfaces when air cools to saturation. Smoke, pollen and fine sea-salt particles can also serve the same function. Pure oxygen and argon are gases, not solid surfaces, so they do not normally provide nuclei by themselves. In this single-answer question, dust particles are the intended example.
