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.
Pure water boils at 100 Â°C (212 Â°F) at earth's standard atmospheric pressure. The boiling point is the temperature at which the vapor pressure is equal to the atmospheric pressure around the water. Because of this, the boiling point of water is lower at lower pressure and higher at higher pressure.
