Motion Of Air
Example: Drying your hair with a hair dryer,The moving air from the hair dryer removes themolecules of liquids as soon as they escapefrom the surface of your hair.
You cool faster in moving air than stillair
Humidity Of Surrounding Air
Example: Wet clothes do not dry easily when airis damp and skin feels dry in airconditionedroom.
Temperature
Evaporation can occur at any temperature
Increase in temperature = increase in rate ofevaporation
Warmer liquid
Greater number of molecules at the surfacelayer are energetic enough to escape
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
