How are bubbles created?

What are air bubbles?

In the typical coke can analogy. As you open the can carbon dioxide goes out as bubbles. Are bubbles created when there is a sudden change in pressure. Emphasis on sudden there.

Thanks for the help

Yes, just as in 1986, when Lake Nyos, saturated with CO2 from volcaniic action, suddenly "exploded" and asphyxiated over 1800 people in Cameroon.

Hi sameeralord!

From http://en.wikipedia.org/wiki/Nucleat..._of_nucleation …

Bubbles of carbon dioxide nucleate shortly after the pressure is released from a container of carbonated liquid.

See the same page for more details.

(For other interesting facts about bubbles, see the physicstoday article at http://scitation.aip.org/journals/do...s_2/36_1.shtml … and you gotta read http://en.wikipedia.org/wiki/Diet_Co...entos_eruption!
