What is the difference between boiling and evaporation?

Amantle Duta

hello my name is Amantle Duta in Botswana .... and um asking for your help on Physics.

May you fully explain the differences between evaporation and boiling.


In boiling, most or all of the molecules in the liquid have enough energy to leave the liquid and become gas. The whole liquid will be near or at the boiling temperature.
In evaporation, the liquid will normally be much cooler than boiling temperature. However, because of the way that molecules pass energy from one to another (Brownian Motion), not all the molecules will have the SAME energy. In fact, some will have lots more than others. These very energetic molecules, if they are near to the edge of the liquid, may have enough energy to escape from the liquid and become gas. The process of molecules leaving will gradually mean that the liquid all evaporates away.
Hope that helps

Boiling is a state of water where it reaches to a limited temperature where it bubbles and get purified. And coming to evaporation the state of temperature is increased so that water present in it automatically evaporates due to high heat.
