Detailed Solution

The increase in surface area increases the evaporation rate of any liquid.
Evaporation is the process where the liquid state of a substance gets converted to the vapour/gaseous state—the evaporation rate increases as the surface area of the liquid increases. For example, when we spread a shirt in the air, the evaporation process is enhanced as the surface area of the wet shirt exposed to air increases.
