Here's a breakdown:

* Boiling: This occurs when a liquid reaches its boiling point, where the vapor pressure of the liquid equals the surrounding atmospheric pressure. Bubbles of vapor form within the liquid and rise to the surface.

* Vaporization: This is a broader term that encompasses both boiling and evaporation. Evaporation is the slower process where liquid molecules gain enough energy to escape into the gas phase at the liquid's surface.

While both processes involve a change from liquid to gas, boiling is a much faster process due to the formation of vapor bubbles throughout the liquid.
