Capillary in a slanted tube with a bend
So I've read a question on here about Capillary action in a slanted tube, but my question goes a little further. Firstly though, could someone explain to me what is meant by the only answer to that question. The answer states that the lift force…

Capillary tube and mercury going up
My question is quite straight forward:
What forces are pushing mercury up a capillary tube and then preventing it from going higher as tube gets thinner?
Setup:
We've got a container filled with mercury and a capillary tube placed in it

Capillary action in different tube diameters with mercury
Imagine we put two glass tubes in a container bulged with mercury.
These tubes have 2 radii which we call them :
1.Big
2.Small
The height of mercury column in the big one is more than the small one.
And the opposite happpens in a water…

Capillary action in the presence of pin holes
Assume that capillary forces are sufficient to draw a fluid up a tube. Now repeat the experiment with very tiny pin-holes in the tube. The question: do the pin-holes limit the capillary action? Or do the capillary forces allow the fluid to span…

where does the energy for capillary action come from?
I think capillary action occurs because water molecules have a little magnetic field with poles so they can stack up on each other somewhat. When it happens though, where is the energy derived from to create this kinetic movement?

Angle of contact in a capillary tube?
Why the angle of contact of water and glass is 0. According to the capillary action why the angle of contact of water and glass is 0.

Why does solder wick absorb solder?
Solder wick is basically just braided copper wire that absorbs molten tin solder in contact. But how does it work? The molten solder is very effectively sucked into the braids. The same effect is not achieved by just one thick strand of wire. I'm…

Capillary action
I've learnt that capillary action is caused by forces acting on molecules near the interface between solids, liquids (and gasses as well). But there are few things I don't understand.
Imagine we have water in a glass container as shown in the…
