Question

How does increasing humidity impact the rate of evaporation? Please Explain.

A. It speeds up the rate of evaporation.
B. It slows down the rate of evaporation.
C. In humidity, our body is unable to sweat.
D. It doubles the rate of evaporation.

Answer 1

When temperature and wind speed are constant, but humidity increases, the rate of evaporation will decrease. When wind speed and humidity stay constant, and temperature increases, then the rate of evaporation will increase because warmer air can hold more water vapor than colder air.

Step-by-step explanation:

So the correct answer is B

Answer 2

"It slows down the rate of evaporation."

Explanation:

By humidity, we are actually talking about the relative humidity and this is inversely proportional to the evaporation. Relative humidity can tell us the amount of vapour that the atmosphere contains in comparison to the maximum that can be possible.

When the weather is hot, our bodies are kept cool through the processes of sweating and breathing. As high levels of humidity inhibit the evaporation, we feel more hot at a given temperature if the level of humidity is high. Hot air is known to hold more vapour when compared to cold air.
