Which of the following can slow evaporation?

Answer and explanation

Correct answer: More humidity

Evaporation becomes slower when the surrounding air already contains a large amount of water vapour. High humidity means that the difference between the moisture at the water surface and the moisture in the air is smaller, so fewer molecules escape into the air. This is why wet clothes may dry slowly on a humid day. In contrast, higher temperature gives molecules more energy, wind removes moist air near the surface, and a larger open surface allows more water to escape at once.

Option B is correct because greater humidity reduces the capacity of air to accept additional water vapour under the same conditions. Option A generally speeds evaporation by replacing moist air with drier air. Option C usually increases evaporation by supplying heat, and option D increases the exposed area. These factors can vary in strength, but among the choices, high humidity is the clear slowing factor.
