Question:

What will the effect on rate of evaporation if surface area increases?

Options:

Rate of evaporation decreases

Rate of evaporation increases

Rate of evaporation remains same

Effect can't be predicted

Correct Answer:

Rate of evaporation increases

Explanation:

The correct answer is option 1. Rate of evaporation increases.

The rate of evaporation will increase if the surface area increases.

Here's why:

Evaporation occurs when molecules at the surface of a liquid escape and enter the gaseous phase.

With a larger surface area, there are more molecules at the liquid's surface that have the opportunity to gain enough energy and transition into a gas.

Imagine a puddle compared to a wide, shallow dish holding the same amount of water. The dish will have a larger surface area, allowing for more water molecules to evaporate at a faster rate.
