In what form does water appear when frost forms?
Answer and explanation
Correct answer: Ice crystals
Frost forms when the surface temperature is below freezing and water vapour changes directly into a solid. Therefore, water appears as ice crystals in frost. Dew is the closest distractor, but it consists of liquid water droplets. Exam tip: below-freezing temperatures favour frost rather than dew.
