Nature Of Liquid

Motion Of Air

Humidity Of Surrounding Air

Area of Exposed Area

Temperature

The rate of evaporation increaseswhen there is more exposed surfacearea

Evaporation only takes place atthe exposed surface area of aliquid

The larger the exposed surface area, themore molecules can escape from theliquid

Rate of evaporation decreases withincreasing humidity and increases with lowerhumidity.

Example: Mercury hardly evaporates at roomtemperature as it has a boiling point of 357degrees Celsius.

Rate of evaporation is faster with moving airpresent

Liquids with a lower boiling pointevaporate faster
