Basis of differentiation | Evaporation | Boiling |
Definition | Evaporation is a natural process in which liquid is vaporized into a gas form | Boiling is a process in which liquid is vaporized when it is heated to its boiling point. |
Occurrence | Vaporization usually occurs from the surface of the liquid. | Boiling usually occurs throughout the mass of the liquid on being heated continuously. |
Rate of vaporization | Rate of vaporization is slow. | Rate of vaporization is faster |
Presence of bubbling | Bubbling is absent | Bubbling is present |
Dependence on temperature | Evaporation is independent of temperature – it can occur at any temperature | Boiling is highly dependent on temperature – it can occur only when the temperatures reaches the boiling point of the liquid and remains constant |
Effect on temperature of the liquid body | Temperature of the liquid body is lowered when evaporation takes place | Temperature of the liquid remains constant throughout the boiling process |
