Here's a breakdown:

* Evaporation: The process where a liquid changes into a gas at the liquid's surface. This happens when the liquid molecules gain enough energy to overcome the attractive forces holding them together and escape into the air.

* Boiling: A specific type of evaporation where the liquid changes into gas throughout the entire liquid, not just at the surface. This happens when the liquid reaches its boiling point, which is the temperature at which the vapor pressure of the liquid equals the surrounding atmospheric pressure.

So, while both evaporation and boiling involve a liquid turning into a gas, evaporation can happen at any temperature, while boiling only happens at a specific temperature.
