Which of the following processes involves the direct conversion of solid snow or ice into water vapor without passing through the liquid phase?

💡 Solution & Explanation

Sublimation is the thermodynamic phase transition in which a substance changes directly from a solid state to a gaseous state without passing through the intermediate liquid phase. Condensation refers to the conversion of water vapor into liquid water droplets, while advection involves the horizontal transfer of atmospheric properties like heat and moisture. Sublimation commonly occurs in high-altitude mountain environments where low atmospheric pressure and dry winds accelerate ice loss.
