Evaporation and Boiling
By : Asad Ali Arshad
Difference between Boiling and Evaporation:
Boiling | Evaporation |
Takes place only at a particular temperature at which the vapour pressure of the liquid becomes equal to the atmospheric pressure.
|
Occurs spontaneously at all temperature. In all seasons whether it is winter or summer.
|
Involves the formation of bubbles of the vapour throughout the bulk of the liquid.
|
Takes place only at the surface of the liquid.
|
Also we can saw evaporation is a process in which a substance changes its state from the liquid state to gaseous state.
|
Evaporation is a process whereby the water is changing into vapour without boiling.
|
It is a quick process.
|
It is a slow process.
|
Bubbles are formed.
|
No bubbles are formed.
|
Occurs at a specific temperature.
|
Occurs at all temperature.
|
Source of energy needed.
|
Energy supplied by surrounding.
