Question

The rate of evaporation increases as ____________ .
A. The exposed surface area of the liquid increases
B. The exposed surface area of the liquid decreases
C. The movement of air above the surface of the liquid decreases
D. Atmospheric pressure increases

Answer 1

In the given question firstly we have to define who exactly was the evaporation and then we can give the proper definition of what is the factor that leads to it. Although the more surface area would tend to large heat absorption.

Complete answer:
The given question statement asks about the entire process through which we would be able to get the proper and correct explanation of the rate of evaporation and the factors affecting it. So we have to explain what exactly are the reasons for the rate of evaporation and also the correct answer of the problem among the following.
Evaporation is the name given to the phenomenon of the type of vaporization of any liquid substance that occurs from the surface of liquid into gaseous phase. Apart from that it is important that it is not saturated with the evaporating substance. Substance or liquid that has a larger surface area will also tend to evaporate faster as we know that due to that there would be more surface molecules per unit of volume that are potentially able to escape the substance.
The correct answer for the given question would be: The exposed surface area of the liquid increases.
Therefore we can say that the answer would be option A, The exposed surface area of the liquid increases.

So, the correct answer is Option A.

Note: For molecules of a liquid to evaporate, they must be located near the surface, they have to be moving in the proper direction, and have sufficient kinetic energy to overcome liquid-phase intermolecular forces. Since the kinetic energy of a molecule is proportional to its temperature, evaporation proceeds more quickly at higher temperatures.
