Pressure inside a bubble/drop of water due to surface tension
I was studying problems in capillary action in fluid mechanics and I have a fundamental doubt. Is the excess pressure inside a bubble/spherical fluid body caused by surface tension, the same all ...

How to calculate pressure necessary to push air bubble out of capillary [closed]
An air bubble is kept by surface tension at the bottom of a capillary. The capillary is sealed at the bottom, where the air bubble sits.
How to calculate the pressure necessary to push the air bubble ...

What would happen to a soap bubble if there were no surface tension?
Suppose you have a soap bubble. Now, suppose that the surface tension in the liquid film that surrounds the bubble disappears instantly. What would happen to the bubble? Also, is it possible to form a ...

Why does a bubble created in the body of a liquid pop when it rises to the surface?
Suppose you have a glass of water and you blow bubbles in the water using a straw. The bubbles pop when they rise to the surface of water. Why does this happen? Does the surface tension of water play ...

How do bubbles on water surface merge?
When we open a tap over a water surface, we get to see a lot of bubbles ("half merged in the water") coming out on the surface.
Now what I saw was that two such nearby half bubbles merge to ...

Why are water bubbles created at the top of the bottle if the water level is higher?
Water bubbles created at the top of the bottle if the water level is higher:
but water bubbles is not created at the top of the bottle if the water level is lower:
This question is very different ...

How does a bubble pop?
I was looking at some old slow motion videos showing a phenomenon where a bubble is popped by firing a sphere (or pea) through it.
One obvious thing that happens is that the pea does not pop the ...

Inverting a bubble interface to recover the level set function
I have access to some high quality CFD data that includes 2D and 3D level set functions for simulations of bubbles. Masking the level set function using a heaviside is easy and it is a fast way to get ...

How are curved soap films stable?
How do curved soap films remain in equilibrium, if surface tension tries to pull them taut?
What I understand:
Surface tension acts tangentially on a surface.
The potential is energy is proportional ...

What are Bubbling Geometries?
I know that Wilson loops in certain higher rank representations are dual to Bubbling Geometries. Also, certain local operators are dual to this kind of solutions. But (independently from holography), ...

Potential energy of a gas lighter than air
Here is the situation. Let's say I have have a mass of a given liquid and I heat it to create a gas. The gas has a lower density than air, so it will move higher and higer in the atmosphere. Then, I ...

How are bubbles formed when a raindrop hits a flat pool of water?
I have noticed that raindrop impact can create a bubble on the surface of the water in a hot tub (104°F) up to several centimeters in diameter that is stable for several seconds before bursting.
The ...

Electron as a wave function, is it a wave bubble? [closed]
Something I have been pondering.
We tend to think of a physical particle as a grain of sand or at atomic levels maybe an electron(lepton).
If I now choose to consider an electron as a wave, typically ...

In beer, why do bubbles travel faster upwards in the center?
This is a very odd question, but I just so happened to be observing a pint of beer and realized that the bubbles floating up seemed to travel faster towards the center of the glass than towards the ...

Can real particles be created from a false vacuum spontaneously through decay?
Consider false vacuum decay.
Given the energy difference between the false to true,
Can this process lead to the creation of real particles as well as the vacuum bubbles?
