Dew on leaves in the morning and its disappearance by afternoon shows which sequence?

Answer and explanation

Correct answer: Condensation at night and evaporation during day

Answer: A. After sunset, leaves lose heat by radiation and may become cooler than the surrounding air. If the leaf temperature falls to the dew point, water vapour near the leaf condenses into liquid droplets called dew. After sunrise, solar heating raises the leaf temperature. The droplets then receive energy and evaporate back into the air, so they disappear by afternoon if conditions remain suitable. A gives the correct night-to-day sequence. B reverses both processes. C is wrong because dew is not necessarily produced by rainfall or snowfall. D is incomplete because pressure change alone does not explain the droplets and their daytime loss. Memory cue: cool night makes dew; warm day removes it by evaporation.
