What is the effect of increasing the surface area of a liquid on evaporation?

Answer and explanation

Correct answer: Evaporation increases

Evaporation is a surface phenomenon in which higher-energy molecules escape from the exposed surface of a liquid into the gas phase. When the same amount of liquid is spread out, its exposed surface area becomes larger, so more molecules can escape at the same time. Consequently, the rate of evaporation increases, making option A correct, provided temperature, wind, and humidity are otherwise comparable. Increasing surface area does not stop evaporation, convert the liquid into a solid, or change its chemical identity into an element. This explains why water spreads or dries faster in a shallow dish than in a narrow container.
