Solution

Evaporation is a process where liquid turn into vapor. Example is “water evaporated from the soil"

Boiling means rapid vaporization of any liquid. It happens when a liquid is heated to its boiling point. The boiling occurs in three different stages such as nucleate boiling, transition boiling and film boiling. There are no stages for evaporation. Boiling

Definition of these two
Boiling is vaporisation of liquid into gas due to continuous heating. Most of the time it is not a natural process. EVAPOURATION

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
