What are the differences between evaporation and boiling?
Posted April 14, 2023
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 |
Examples |
- Drying of wet clothes or any wet surface - Melting ice cubes |
- Heating water, oil, or any other liquid using a heating source |
