Question
How will you differentiate between evaporation and boiling?
Solution
|
Evaporation |
Boiling |
|
1. It is slow process |
1. It is a fast process |
|
2. Evaporation occurs spontaneously at all temperatures. |
2. Boiling occurs at the boiling point at which the vapour pressure of the liquid is equal to the atmospheric pressure. |
|
3. Evaporation takes place only at the surface of the liquid |
3. Boiling involves the formation of bubbles of vapour below the surface of the liquid. |
|
4. The rate of evaporation increases by increasing the surface area |
4. Surface area has no effect on the rate of boiling. |
