What is difference between evaporation and boiling?

The main differences between evaporation and boiling are as follows: 1. Evaporation takes place at all temperatures, while boiling occurs at a particular temperature. 2. Evaporation takes place from the surface, whereas boiling occurs throughout the liquid volume. 3. Evaporation produces cooling effect but boiling does not. 4. Evaporation is a slow process while boiling is a rapid process. read less

Evaporation occurs on the surface of liquid and it is a vaporization of liquid. It is a state of transition from liquid to gaseous state. The process occurs slowly and cannot be seen as well. It occurs when there is exposure of water to air and water molecules change into vapor and these vapors rise up and form clouds. Boiling occurs on the entire mass of liquid and it is the vaporization of liquid. It occurs rapidly. It happens when the vapor pressure of the liquid is equal to the pressure exerted by the environmental pressure on liquid. It is a state of phase transition. The boiling occurs in three different stages: nucleate boiling, transition boiling and film boiling. There are no such stages for evaporation. Boiling occurs when the temperature of the liquid is greater than the boiling point of the substance. Evaporation can occur at any temperature. read less

Evaporation takes place from the surface, whereas the entire liquid boils. 3. Evaporation can occur using the internal energy of the system, while boiling requires an external source of heat. 4. Evaporation produces cooling but boiling does not. 5. Evaporation is a slow process while boiling is a rapid process. read less
