Write down an e× ample to know how the following factors influence the rate of evaporation.

(a) Surface area

(b) Wind

(a) If we take same quantity of water, one in a large surface are beaker and other in beaker having small surface area. We will keep both the beakers in sunlight, after few hours we will observe that quantity of water has decreased in the beaker having large surface area. Hence, increase in the surface, increases the rate of evaporation.

When we increase the surface area more no. of water molecule is e× posed to air, allowing water molecule to acquire more energy/heat from the surrounding. This energy helps molecule break hydrogen and other type of bond.

The progression is essentially more area more heat absorption increased kinetic energyincreased movementfaster Evaporation.

(b) On a windy day, the clothes dry faster than on a non-windy day. Hence, wind increases the rate of evaporation.

The wind sweeps away the airborne water particles that are in the air. The humidity of the air in the region is reduced, which allows more water molecules to dissipate in the air.
