    Bubbles Formation
AI Thread Summary
Bubbles form on the water surface primarily due to nucleation, where gas molecules gather to create bubbles, often influenced by temperature and pressure changes. The pressure inside the bubbles can exceed atmospheric pressure, causing them to rise. However, surface tension can trap these bubbles at the surface, preventing their escape. The discussion highlights the complexity of this phenomenon, particularly in distinguishing between bubble formation in water versus carbonated beverages. Understanding these principles can clarify why bubbles appear in various contexts.

Homework Statement


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.


Homework Equations





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?

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
