Question
State three differences between evaporation and boiling
✓
Answer
| BOILING | EVAPORATION | |
| Definition of these two terms | Boiling is vaporisation of liquid into gas due to continuous heating. Most of the time it is not a natural process. | Evaporation on the other hand is a natural process and it is similar to boiling , but the liquid form changes into gaseous form when there is a increase in either temperature or pressure or both. |
| Occurrance | Large mass | only on surface |
| Amount temperature involved | Boiling happens when the temperature reaches to the boiling point. | In Evaporation the temperature does not need to reach to boiling point |
| Bubble Formation | Bubble formation is visible | Bubbles do not form in evaporation |
| Energy | Usually external source of energy is needed for boiling to happen. | Most of the time energy for evaporation is supplied by the atmosphere or surrounding. |
| Length of the process | Rapid Process | Slow process compared to boiling |
