Why is it scientifically wrong to call mist only water vapour?

Answer and explanation

Correct answer: Mist is made of visible tiny water droplets

Answer: A. Water vapour is water in the gaseous state and, as a gas mixed with air, it is normally invisible. Mist, in contrast, is visible because it contains very small liquid water droplets suspended in air; under sufficiently cold conditions, ice particles may also be involved. The droplets scatter light and reduce clarity, which is why mist can be seen. A is correct because it identifies the physical form that makes mist visible. B is false: water vapour is not always coloured and is generally invisible. C is false because mist is an atmospheric water phenomenon, not rock. D is false because mist consists of droplets suspended in air, so air is present. Memory cue: vapour is invisible gas; mist is visible condensed water droplets.
