Question

2. Which of the following factors can affect the rate of evaporation of water?
a. Wind
b. Exposed surface of water
c. Humidity
d. Both (a) and (b)

Answer 1

Answer:

The rate of evaporation is affected by the following factors: Temperature: The rate of evaporation increases with an increase in temperature. Surface area: The rate of evaporation increases with an increase in surface area. Humidity: The amount of water vapour present in the air is called humidity.

Answer 2

Explanation:

The greater is the humidity of the atmosphere which is surrounding the water molecule, the rate of evaporation is slow. Thus, the rate of evaporation depends on the surface area, temperature and humidity. Therefore, the correct option is D.
