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

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.
