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.
1 For example, when a pot of water is kept boiling, the temperature remains at 100 Â°C (212 Â°F) until the last drop evaporates, because all the heat being added to the liquid is absorbed as latent heat of vaporization and carried away by the escaping vapour molecules.
