Question

What happens to the rate of evaporation when there is more exposed surface area of liquid?

• A. It decreases gradually
• B. It increases
• C. Remains same
• D. It decreases rapidly

Answer 1

The correct option is B It increases

Evaporation is a process in which some molecules of a liquid, which have greater kinetic energy, escape from the liquid and enter the atmosphere.

When the surface area exposed is more, the molecules get greater opportunity to escape. Hence more molecules escape and rate of evaporation increases.
