→ Boiling Point : Boiling is a bulk phenomenon. 


⇒ It occurs at a particular temperature.


⇒ The temperature at which liquid starts boiling to change into steam or vapour. 



⇒ Boiling happens when the temperature reaches to the boiling point.



→ Evaporation : Evaporation takes place at all temperatures.


→ Evaporation is when a liquid changes to a vapor, caused by an increase in temperature and / a decrease in pressure.
