Tabulate the differences between evaporation and boiling
Answers
Evaporation is a process in which the liquid state is converted into gaseous state due to increase in temperature.
Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point.
Boiling:-
▼ During boiling, a liquid changes into a gaseous state at a constant temperature, called its boiling point
▼ This process needs an external source of heat energy
▼ It is a bulk process in which the gaseous state is formed form all parts of the liquid followed by the agitation of the liquid
▼ The boiling doesn't cause cooling
▼ Boiling of a liquid is good indicator of the strength of intermolecular forced between the molecules of a liquid
Evaporation :-
▼ During evaporation, a liquid. Changes into a gaseous state at any temperature below its boiling point
▼ this phenomenon doesn't need any external source of heat energy
▼ it is not a bulk process in which the gaseous state is formed from only the exposed state is formed form only the exposed surface of the liquids
▼ The evaporation causes cooling
▼ Evaporation of the liquid is a spontaneous phenomenon so does not indicate any such strength
