Question

Which of the following decreases the rate of evaporation?
  1. Increase in wind speed
  2. Increase in temperature
  3. Increase in humidity
  4. Increase in surface area

A
Increase in wind speed
B
Increase in surface area
C
Increase in temperature
D
Increase in humidity
Solution
Verified by Toppr

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.
Hence C is correct answer
