If a day is hot and dry, how may evaporation be?

Answer and explanation

Correct answer: Fast

Correct answer: A, fast. Evaporation is the change of liquid water into water vapour from a surface. Heat gives water molecules more energy, so more molecules can escape from the liquid surface. Dry air contains less water vapour, creating a larger difference between the vapour at the wet surface and the surrounding air; this generally favours faster evaporation. Wind and a larger exposed surface can also increase the rate, although the question focuses on hot and dry conditions. Option A is correct. Option B is wrong because heat and dryness usually speed evaporation rather than greatly slowing it. Option C is wrong because evaporation can occur whenever liquid water is present, even if the rate varies. Option D is wrong because evaporation is not restricted to night; it often increases during warm daylight. Memory cue: hot supplies energy, dry air accepts more vapour.
