Question

What is the effect of increase in surface area on the rate of evaporation?

Answer 1

Evaporation:

• Evaporation is the phenomenon in which a substance changes its state from liquid to gas by applying heat.
• Evaporation is a surface phenomenon because in this the above water will evaporate from the whole water.

Effect of surface area on evaporation:

• Evaporation increases with the increase in surface area. It is because, the larger the surface area that is exposed to air, the more molecules will escape into the air.

Hence, rate of evaporation increases with an increase in surface area.
