What is the main difference between dew and frost?
Answer and explanation
Correct answer: Dew is a deposit of liquid water droplets, whereas frost is a deposit of ice crystals
Dew forms when a surface cools to the dew point and water vapour condenses into tiny liquid water droplets. Frost forms when the temperature is below freezing and water vapour deposits directly as ice crystals. Option A is incorrect because dew is not a gas; it is liquid water. Exam tip: dew means liquid droplets, while frost means ice crystals.
