The change of a liquid into vapour at any temperature below its boiling point is called evaporation. Evaporation is a surface phenomenon. Particles from the surface gain enough energy to overcome the forces of attraction and changes to vapour state. Factors affecting evaporation :- The rate of evaporation depends upon surface area, temperature,humidity and wind speed. Increase in the surface area increases the rate of evaporation. Increase in temperature increases the rate of evaporation. Increase in humidity decreases the rate of evaporation. Increase in wind speed increases the rate of evaporation. 1a)Evaporation is a * bulk phenmenon inter facial phenomenon both i and ii are correct both i and ii are wrong
