Boiling is the "rapid vaporization of liquid" when the liquid is heated at the point where the pressure of the vapor is equal to the pressure exerted by the atmosphere in the liquid.
So during the boiling, the vaporization of the water is also occurring but is a little bit more complex.
Some questions that you may ask your friend to differentiate those two phenomena are:
Which one is used to cook things like pasta? (boiling)
in which process, a liquid is transformed into a gas? (evaporation)
Which one includes the other? (boiling) ;
Evaporation and boiling are both phases changes, but they differ in the specifics of how and when they happen. These differences involve the temperature and location within the liquid where they occur, as well as the speed of the process. ;
To differentiate between evaporation and boiling, ask questions about temperature conditions, locations of the process, rates of occurrence, volume changes, and pressure conditions. This will help clarify that boiling happens rapidly at a particular temperature throughout the liquid, while evaporation occurs slowly at the surface and can happen at any temperature. Understanding these differences allows for a clearer grasp of both processes.
