When you’re boiling a pot of water, right before the water starts to boil if you watch carefully at the bottom of the pot there will be tiny bubbles that form and disappear. Why do they just disappear instead of floating up to the top once they’re already formed??

Answer 1

TLDR for the whole thread…..the bubbles (water vapor) get to cooler temps away from the heat source and the vapor reverts back to a liquid.
