Answer for screen readers
The final answer is boiling.
More Information
Boiling occurs when the vapor pressure of the liquid equals the atmospheric pressure, allowing liquid particles to escape into the gas phase. This is distinct from evaporation, which occurs at the surface at temperatures below boiling point.
Tips
A common mistake is to confuse boiling with evaporation. Boiling occurs throughout the liquid at a specific temperature, while evaporation happens on the surface at all temperatures.
