Why Do Things Boil?

Why does something boil?

Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point, the temperature at which the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere..

Why bubbles are formed during boiling?

Boiling begins near the source of heat. When the pan bottom becomes hot enough, H2O molecules begin to break their bonds to their fellow molecules, turning from sloshy liquid to wispy gas. The result: hot pockets of water vapor, the long-awaited, boiling-up bubbles.

At 40°C (104ºF) the presence of oxygen dissolved in the water is already so low that there is almost no difference between oxygen levels at that temperature and at the boiling point.
