does carbonated water boil?
Do the bubbles in carbonated water result from the CO2 boiling?
According to E2 carbonated water is 'a suspension of H2O-CO2'. What the hell does that mean?
According to Howstuffworks '[m]any different gases dissolve in liquids, and we see an example all the time in carbonated beverages. In these beverages, there is so much carbon dioxide gas dissolved in water that it rushes out in the form of bubbles'.
So the answer is no, the bubbles result from the CO2 (in gas form at room temperature) not remaining disolved in water at sea level pressure.
O2 on the other hand (also a gas at room temperature), does remain dissolved in water at sea level pressure.
The question is, at what altitude will O2 spontaneously bubble from normal water?
One of my great (and few) regrets is that I've lost my high school math, physics and chemistry so irretrievably.
