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?
