Difference Between Evaporation And Boiling Of Water. Evaporation is the changing of a liquid into vapours gaseous state from the surface of the liquid without heating it Take some water in a dish. Boiling and evaporation are similar in that both describe a substance changing from liquid phase to gaseous phase.
Jul 06 2011 Evaporation is the process by which the water surface absorbs heat. Another difference is evaporation takes place only at the surface of the liquid while the boiling is a bulk process where vaporization takes place throughout the liquid. The major key difference to be noted between Evaporation and boiling is that of the occurrence Evaporation occurs only on the surface of the liquid whereas Boiling occurs over the large mass of the liquid.
Boiling is the process by which the internal energy of the molecules of water is increased until it reaches the boiling point and it changes to a gaseous state after 100 degrees centigrade.
Strictly speaking there is difference between the two processes. For instance when you dry your clothes in the sun the water evaporates from them. Evaporation occurs on the surface of the liquid whereas boiling occurs in the liquid in its entirety. This is categorized as the key difference between Evaporation and Boiling.
