    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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
