Why Do Bubbles Form on the Water Surface?

In summary, the conversation is about the phenomenon of bubbles forming on the surface of water and the question of whether there is a scientific explanation for it. The person asking the question has researched the concept of nucleation but finds it difficult to understand. They provide a link to an article discussing the formation of bubbles in fizzy drinks, but they are unsure if it applies to bubbles in water. Another person suggests that the pressure inside the bubbles may cause them to rise to the surface but surface tension prevents them from escaping.

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?

FAQ: Why Do Bubbles Form on the Water Surface?

What causes bubbles to form?

Bubbles form when a gas, typically carbon dioxide, is trapped in a liquid and released as a result of a disturbance or change in pressure.

Why do bubbles always form in the same shape?

Bubbles form in a spherical shape due to the surface tension of the liquid. This shape allows for the smallest surface area and therefore the lowest energy state.

How do bubbles behave in different liquids?

Bubbles behave differently in different liquids due to differences in surface tension and viscosity. For example, bubbles in water tend to rise and pop quickly, while bubbles in honey rise more slowly and can last longer.

Can bubbles form in a vacuum?

Yes, bubbles can form in a vacuum if there is a liquid present. However, the lack of air pressure outside the bubble may cause it to expand and eventually burst.

What factors affect the size of bubbles?

The size of bubbles can be affected by the amount of gas released, the surface tension of the liquid, and external factors such as temperature and pressure. Bubbles may also merge or split depending on these factors.
