Condensation

                              Condensation 

Condensation is the change of the physical state of matter from the gas phase into the liquid phase, and is the reverse of vaporization. The word most often refers to the water cycle .

                               

          

Cycle  of  condensation : 

                     Condensation is the process by which water vapor in the air is changed into liquid water. ... These clouds may produce precipitation, which is the primary route for water to return to the Earth's surface within the water cycle. Condensation is the opposite of evaporation .

         

             

                 

In condensation, matter changes from a gas to a liquid. All matter is made of tiny moving particles called molecules. Evaporation and condensation happen when these molecules gain or lose energy. This energy exists in the form of heat .

Example of condensation : 

Common examples of condensation are: dew forming on grass in the early morning, eye glasses fogging up when you enter a warm building on a cold winter day, or water drops forming on a glass holding a cold drink on a hot summer day. Condensation occurs when water droplets form due to cooling air.
