Difference between evaporation and boiling
==================================================================
• Evaporation:-
1) Evaporation is the process of conversion of a liquid into vapours at any temperature below its boiling point.
2) In the process of evaporation, bubbles are not formed.
3) It is slower than the process of boiling (Slow process).
4) It occurs at all/any temperature.
5) In the process of evaporation, temperature may change.
6) Energy supplied by the surroundings.
• Boiling:-
1) Boiling is the process by which a liquid turns into a vapor when it is heated to its boiling point.
2) In the process of boiling, bubbles are formed.
3) It is faster than the process of evaporation (Quick process).
4) It occurs at a definite/fixed temperature (boiling point).
5) In the process of boiling, temperature remains constant.
6) Energy supplied by a source of energy.
Evaporation is a normal process that occurs when the liquid form changes into the gaseous form; while causing an increase in the pressure or temperature.
Boiling is an unnatural process where the liquid gets heated up and vaporized due to continuous heating of the liquid
