Question

Which condition out of the following will increase the evaporation of water?

• A. Increase in temperature of water
• B. Decrease in temperature of water
• C. Less exposed surface area of water
• D. Adding common salt to water

Answer 1

Answer: (A)

Increase in temperature of water

As the temperature of the water increases, the kinetic energy increases. As a result, the force of attraction between the molecules decreases, and the molecules become more and more separated.

Thus, increasing the temperature of a body of water also often increases evaporation. This is because as the temperature rises, the water molecules begin moving about more rapidly and will finally escape.
