Dew and frost both form on surfaces, so why are they differentiated?

Answer and explanation

Correct answer: Their final physical states are different: dew is liquid and frost is solid

Correct answer: A. Dew and frost have a similar setting: both commonly develop on exposed surfaces after cooling. The important difference is the state of the water at the end. If the surface temperature remains above freezing but falls to the dew point, water vapour condenses into liquid drops called dew. If the surface is at or below freezing, vapour may deposit directly as solid ice crystals, producing frost. B is wrong because water vapour is the source of both forms. C describes suspended fog or mist, not deposits attached to a surface. D is false because dew and frost can form on land, vegetation, and many exposed objects. Memory cue: same surface location, different state—dew is liquid; frost is ice.
