During evaporation, how may the surrounding temperature feel?

Answer and explanation

Correct answer: Cooler

Correct answer: D, cooler. Evaporation is the change of liquid water into water vapour. To escape from the liquid surface, some water molecules need energy, and they take this energy as heat from the liquid and its surroundings. The remaining surface and nearby objects may therefore lose heat and feel cooler. Sweat illustrates this process: when sweat evaporates from skin, it removes heat and produces a cooling sensation. A is not the usual direct effect of evaporation at the surface. B ignores the heat used in the process. C describes dust, which is unrelated to a change of state of water. The amount of cooling depends on conditions such as wind, humidity, and available heat. Memory cue: evaporation takes heat away.
