How come oxygen bubbles form even before water begins to boil?
Thanks
Happy Halloween!

They're not oxygen bubbles? Never knew that lol.

The bottom of the pot is very hot. Some water there will get hot faster, enough to be evaporated, and thus rise to the surface (its density, being vapor, is less than the liquid over it).
These bubbles are not oxygen , but water vapor.

It's not oxygen bubbles, it's bubbles of water vapor. And this is because below the boiling point, some of the water does evaporate.

These are bubbles of air coming out of solution due to the raised temperature, when all gases are less soluble.
