Water boils at 100Â°C at standard pressure, no exceptions! However, the water temperature in the kettle is not even. Around the heating elements, the water rapidly reaches 100Â°C, even if the water in the rest of the kettle is cooler.
This conversion of liquid water to water vapor (steam) is what you see when you're looking at a pot of boiling water. As we all know, for pure water at standard pressure (the air pressure that exists at sea level), the temperature at which this occurs is 212Â°F (100Â°C).
