Question

Which of the following factors increases the rate of evaporation?

• A. Increase in surface area
• B. Increase in temperature
• C. An increase in wind speed
• D. An increase in humidity

Answer 1

Answer: (A), (B), (C)

The correct options are
A Increase in surface area
B Increase in temperature
C An increase in wind speed

• Evaporation is a surface phenomenon, therefore increase in surface area increases rate of evaporation.
• With increase in temperature, more number of particles gets enough kinetic energy to go into vapour state.
• Decrease in humidity results in the increase of rate of evaporation.
• With increase in wind speed, the particles of water vapour move away with the wind which increases the rate of evaporation.
