what noise is the water boiling pot making when boiling water?
I tried to boil water in a Whistling boiling water kettle tea pot on a stove. The stove has electric stove top coil burners. So when boiling water with those, there is some noise and sometime a sudden big noise like something hit the pot. I been living with the phenomenal forever but today, I just wanted to know why? what is the noise that the pot is making?

cavitation noise - The noise produced in a liquid by the collapse of bubbles that have been created by cavitation.

What is the sound of boiling water called?
The word burble was first used in the 1300's, and it probably comes from an imitation of the sound a rippling, bubbling brook makes.What sound does a kettle make when boiling?
Stove-top kettles generally whistle to indicate the water has boiled\u2014indeed, they're often called "whistling kettles", to distinguish them from electric jug kettles. Electric kettles don't usually make a recognisable noise when the water has boiled, they just switch themselves off. whistle is an onomatopoeia?Why does my pot make noise when boiling water?
"The water boils from the bottom up and the smaller, hotter bubbles containing steam at the bottom of the pot are compressed by the colder water on top, causing them to quickly burst at the bottom of the pot and produce the noise that is heard," Hess continued.What is the noise a kettle makes?
Dave - Sounds of the bubbles, as the water is boiling, forming little bubbles of steam and as they rise up in the colder water they shrink and collapse and then smash into one another and make lots of noise. So it gets a lot quieter once bubbles get all the way up to the surface and they stop cavitating.More answers regarding what noise is the water boiling pot making when boiling water?
Answer 2
As the heat source is at the bottom, the water on the surface gets to the boiling temperature earlier than the rest of the pot/kettle. This causes lots of bubbles to form, and as they start moving up they come in contact with colder water and condense immediately.
Please note that, water vapor is much lighter than liquid water. Well... this is the very first reason it starts floating. But also this means all of a sudden there’s an instant increase in volume when the bubbles are forming, this is the first noise you’re hearing. And when these bubbles condense, they pop immediately and this is the second almost simultaneous sound/noise you hear.
Answer 3
You mentioned a "sudden big noise". The metal in the kettle expands as it heats, particularly the metal on the bottom (which is directly exposed to the heat). At a certain point, your kettle's bottom is compressed against the sides and buckles, warping upwards or downwards in a way which relieves the compression. The mechanism of the noise is similar to the clicking noise when you press down on the tamper-evident "safety button" on the lids of some jars.
My guess is that if you press hard on some portion of the base of the kettle (you may need to press from inside the kettle) it'll make the same noise, though probably not as loud because it won't be resonating against the cooktop.
