Which outcome occurs when humidity reaches 100% around finely divided airborne dust?

💡 Explanation

When humidity hits 100%, the **hygroscopic effect** of dust favors water condensation, thereby forming cloud droplets when they serve as cloud condensation nuclei facilitating nucleation because that lowers the energy barrier for phase change, therefore droplet formation occurs rapidly rather than supersaturation alone controlling condensation.
