what makes a tea kettle whistle?

Answer 1

First of all, the cover over the spout is shaped like a whistle on the inside, except that the hole for the steam to come out of is very small. They are made that way because as the water starts to boil, it starts turning into steam, and steam takes up a lot more room than water. Once it is boiling hard enough, not all of it can easily escape through the little hole, and the rest is held inside the teapot where it starts building up pressure, and as the pressure builds, the steam starts moving faster and faster through the hole. Once the pressure and speed have built up enough, it is just like you blowing into a whistle. I hope this helps.
