Under which condition can air reach saturation quickly?

Answer and explanation

Correct answer: Moist air cools rapidly

The correct answer is B: moist air cools rapidly. Saturation means that air contains as much water vapour as it can hold at its current temperature. When moist air cools, its capacity to hold water vapour decreases. If enough cooling occurs, the actual vapour content reaches the reduced saturation capacity, and relative humidity becomes 100 percent. Further cooling may begin condensation, provided suitable surfaces or condensation nuclei are available. A is wrong because rising temperature generally increases vapour-holding capacity while decreasing moisture here. C is wrong because hot, dry air is far from saturation. D is wrong because the absence of a water source does not itself make air saturated. Rapid cooling may occur when air contacts a cold surface or rises and expands, but the option only needs the core condition. Memory cue: to reach saturation, either add moisture or cool the air; cooling moist air is the fastest choice here.
