ever listened to water boil?
it can be a kettle of water heating up, or a pot of water on the stove. just when the water is starting to heat up, and u can see tiny bubbles forming, do u hear a metallic "clicking" sound?
"oscillating/unstable/always expanding and contracting" bubbles produce snapping sounds when they collapse/break down; that's how the deep sea snapping shrimp make their sounds. i feel that the sounds i hear from the heated up water is due to such oscillating microbubbles too. the very first bubbles that form are the tiniest ones, and the later "generations" of bubbles are bigger. so when these tiny bubbles collapse, they make the snapping sound.
or can anyone tell me why there are clicking sounds when u are boiling a pot of water?
