| Boiling of liquid | Evaporation of liquid |
| i. | Boiling of liquid takes place at boiling point which is fixed for a given pressure and unique for a given liquid. | Evaporation of liquid can take place at any temperature. |
| ii. | It occurs throughout the liquid. | It occurs only at surface of liquid. |
| iii. | The process does not depend on area of liquid surface exposed. | The process depends upon area of liquid surface exposed. Higher the exposed surface area, higher the rate of evaporation. |
| iv. | Source of energy is needed. | Energy is taken from surrounding. |
| v. | Boiling does not reduce temperature of liquid. | When evaporation takes place, temperature of liquid decreases. |
| vi. | During boiling process, bubbles are formed in liquid. | During evaporation, no bubbles are formed in liquid. |
