question 10 (5 points)

Explanation:

Evaporation is the process by which liquid water changes to water vapor. Humidity is the amount of water vapor in the air. When the air is more humid (has more water vapor), there is less "room" for additional water vapor from evaporation. So, increasing humidity slows down the rate of evaporation. Option A is incorrect as there's no basis for doubling. Option B is wrong because higher humidity doesn't speed up evaporation. Option C is about human perspiration (a form of evaporation from the body) but is not directly answering how humidity impacts the general rate of evaporation (the question is more about the physical process, not specifically human - body related in the context of the options).

Answer:

D. It slows down the rate of evaporation.
