| Evaporation | Boiling |
| 1.The process of escaping of molecules from the surface of a liquid at any temperature is called evaporation. | 1.The process in which the liquid phase changes to gaseous phase at constant temperature is called boiling. |
| 2.Evaporation takes place at any temperature. | 2.Boiling takes place at definite temperature. This is called boiling point of that liquid. |
| 3.The temperature of the system gets down. | 3.The temperature of the system increases upto boiling point. |
| 4.The evaporation depends on the surface area, humidity, temperature wind speed. | 4.The boiling depends on the nature of substance. |
| 5. Eg : (1) Wet clothes dries. (2) Sea water evaporates to form clouds. | 5. Eg : (1) Water boils at 100°C. |
