How does water vapour become visible in fog?

Answer and explanation

Correct answer: It condenses into tiny droplets

Correct answer: A. Individual water-vapour molecules are too small to see, so water vapour is considered invisible. When moist air cools sufficiently, or when it reaches saturation, the vapour changes state and condenses into countless tiny liquid droplets. In fog, these droplets remain suspended in the air near the ground rather than immediately falling as rain. The droplets scatter and reflect light, making the misty air visible and reducing visibility. A is correct because it gives the required change of state from invisible vapour to visible droplets. B is wrong because condensation does not turn water into stone. C is wrong because the water remains in the air as suspended droplets. D is wrong because salt formation is not the normal atmospheric process involved in fog. A useful distinction is that vapour is invisible, whereas a collection of droplets can be seen. Memory cue: invisible vapour becomes visible after condensation into droplets.
