What kind of air is useful for mist formation?
Answer and explanation
Correct answer: Moist and cool
Mist forms when moist air cools to its dew point and water vapour condenses into tiny suspended droplets. Therefore, moist and cool air is most favourable for mist formation. Air that is cool but extremely dry lacks sufficient water vapour for condensation. Exam tip: remember that both moisture and cooling to the dew point are needed for mist and fog.
