Question

The rate of evaporation increases with __________.

• A. decrease in surface area
• B. increase in surface area
• C. decrease in temperature
• D. increase in humidity

Answer 1

The correct option is B

increase in surface area

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