If water takes heat from its surroundings during evaporation, what effect can it have on the surroundings?

Answer and explanation

Correct answer: The surroundings may feel cooler

Direct answer: A. Evaporation is a change from liquid to vapour, and it requires energy called latent heat. When the liquid takes this energy from nearby skin, soil, water, or air, that surrounding material loses some thermal energy and may cool. This is why drying sweat can make the body feel cooler. A is correct, though the amount of cooling depends on the energy transfer and conditions. B is wrong because evaporation has no necessary connection with earthquakes. C is wrong because removing heat does not make pressure zero. D is wrong because evaporation adds water vapour to the air rather than making it disappear. Memory cue: evaporation takes heat; condensation gives heat back.
