Evaporation depends on temperature, surface area and weather conditions
a) Evaporation increases if the surface area of the water is large as the number of water molecules at the surface increases. This increases the probability of more water molecules breaking free on acquiring sufficient kinetic energy.
b) Evaporation is more as the temperature approaches the boiling point of water. As the temperature increases the kinetic energy of the molecules increases. This decreases the extra kinetic energy the surface molecules require to break free or evaporate. So evaporation increases.
c) In highly humid weather, evaporation decreases, as the air is highly-saturated with water molecules.
d) As evaporation takes place, the air immediately above the surface of the water becomes saturated with water molecules.
