Answer:
yes. If you leave it boiling at high temperatures for a certain period of time, the steam produced will be too much for the kettle, and that's when you hear the whistling sound. And if you ignore the kettle and leave it continously boiling, there comes a time when the situation falls over the edge, causing the kettle to blow up in 25m diametre. The rate of the procces depends on the size of the kettle and the temperature.
