Which outcome occurs when supercooled liquid droplets encounter ice nuclei in cloud seeding?

💡 Explanation

When supercooled droplets encounter ice nuclei, heterogeneous nucleation occurs because water molecules rapidly bind to the ice surface, releasing latent heat that drives further crystallization. Therefore, initiating further crystallization causes rain, rather than lowered vapor pressure or air density changes as the relevant mechanism is not phase change thermodynamics.
