Question

Which one of the following factors do not affect the rate of evaporation?

• A. Temperature of the liquid
• B. Humidity of the surrounding air
• C. Depth of the liquid
• D. Surface of the liquid

Answer 1

The correct option is C Depth of the liquid

Substance or liquid that has a larger surface area will evaporate faster as there are more surface molecules per unit of volume that are potentially able to escape.

The higher the temperature of substance or liquid, the greater is the kinetic energy of the molecules at its surface, and therefore the faster the rate of evaporation.

If the air is saturated with a great amount of water causing high humidity, it causes low capacity for the evaporating substance.

Hence, option C is the answer.
