Factors affecting the rate of condensation and evaporation.

The factors On which rate of evaporation depends are :

 

 

SURFACE AREA :  We know that Evaporation is an surface phenomenon . Hence with increase in surface area , the rate of evaporation also increases. For example : Wet clothes become dries quickly when spread out
  
TEMPERATURE :   Rate of evaporation Increases with the rise in temperature as increasing temperature increases the kinetic energy of molecules of the liquid which facilitates the molecule to convert into vapour. 

HUMIDITY - The rate of evaporation decreases with the rise in Humidity. Humidity is defined as the amount of the  water vapour in the air . On a particular or defined temperature , air cannot hold or carry defiinite amount of moisture. Hence this high humidity ,  reduces the rate of evaporation as air cannot cannot hold any more water vapour.


When the air is saturated with the evaporating substance or other substances, evaporation is slow. High pressure on a water surface reduces the rate of evaporation. Storms are examples of high-pressure systems that slow down evaporation. At a high humidity, the rate of evaporation is also low.
A high rate of airflow increases evaporation. Large surface areas also facilitate evaporation. An increase in temperature facilitates evaporation by increasing the kinetic energy of the evaporating molecules. However, strong intermolecular forces or bonds reduce the rate of evaporation. This is why boiling water evaporates faster than cold water.
Water evaporating from lakes, rivers and oceans remains in the atmosphere as vapor, which affects humidity. This is why areas with large water bodies and high temperatures have high humidity. In the water cycle, evaporating water forms clouds. The clouds later release the water back to the surface of the Earth in the form of snow or rain. An evaporation equilibrium can occur in a closed area when air is fully saturated with vapor, preventing further evaporation
