Explanation
| Differences between Evaporation and Boiling |
| Evaporation |
Boiling |
| 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. |
| Evaporation usually occurs on the heated liquid’s surface. |
Boiling usually occurs on the entire mass of the heated liquid. |
| The bubbling effect is not visible in evaporation. |
