Why will dew not form if the surface temperature remains above the dew point?

Answer and explanation

Correct answer: Nearby air will not become saturated

Answer: A, nearby air will not become saturated. The dew point is the temperature to which air must cool, at its existing moisture content, for it to reach saturation. If a surface stays warmer than the dew point, the thin layer of air touching it generally also remains above the temperature needed for condensation. Water vapour therefore stays in the gaseous state instead of depositing as liquid dew. Option A is correct because saturation is the necessary step before dew can form. Option B is wrong because water vapour does not immediately become ice merely because the surface is above the dew point; freezing requires temperatures at or below suitable freezing conditions. Option C is unrelated: cloud position does not define the dew point. Option D is wrong because normal dew formation does not require air pressure to disappear. Memory cue: above dew point means no saturation, so no ordinary dew.
