Re: how does a whistling tea kettle work

I can't seem to find who invented it. There are many things that have no known inventor, the whistling kettle is probably one of them. Also am i correct to say that a tea kettle whistles when the heat, which consists of atom, molecules and ions, reaches the boiling poing of 100 degrees and the pressure of the heated water against the inside of the tea kettle turns to water vapor and forces some air out of the small opening (the whistle??) No, you have some VERY confused physics ideas in here ! Heat does NOT consist of Atoms, molecules and Ions, Heat is work or energy. All you are doing is heating water to its boiling point, that point at which its saturated vapour pressure exceeds atmospheric pressure and it begins to turn into a gas (steam) , The higher the flame, of course, the faster steam is produced. The air in the kettle is expelled while the water boils to steam. The higher the flame the faster steam is generated. A kettle can be made to boil so gently that the whistle dosn't get enough gas to make a noise. This link explains in fine detail the answer to the rest of your question, and I am indebted to Dr Louis Bloomfield for his notes, for which I claim no credit. http://rabi.phys.virginia.edu/HTW/violins_and_pipe_organs.html
