about the formation of bubbles
1. The problem statement, all variables and given/known data
Well,actually it isn't related to my hw.I ask this just simply due to my curiosity.
Here's the question:
Sometimes,we saw bubbles formed on the water surface,could anyone explain this phenomenon:)?Any theorey behind it?
thx a lot.
2. Relevant equations
3. The attempt at a solution
um..I have no idea about this question.Pls forgive my foolishness.
I have searched something called nucleation?It is too difficult for me,I can't get it at all.Moreover,it seems to explain about the formation of bubbles in fizzy drinks.How about in water?

If the pressure in the bubbles formed becomes higher hen the atmospheric pressure they might rise to the surface of the water, but surface tension prevents them to escape from the surface.
