What is the boiling water temperature?

Explanation:
Boiling occurs when the liquid’s vapor pressure equals the surrounding air pressure. At standard atmospheric pressure (sea level), that moment is 100°C, so water starts to boil there. The other temperatures describe hot water that is not boiling yet. A higher temperature like 110°C isn’t the boiling point for water at normal pressure (water would already be steam at 100°C); only under higher pressure could water boil at temperatures above 100°C. In typical kitchen conditions, the boiling water temperature is 100°C.
