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.
Answer Heat is being added to ice as it melts, but that heat is going into turning the water from a solid into a liquid (breaking intermolecular bonds), rather than increasing the temperature. This is also true when it boils, and that is why a boiling pot of water won't reach a higher temperature than 100 Â°C.
