Why do gas bubbles appear to get stuck inside narrow vertical tubes?

Sorry, wanna be scientist here, but wouldn't the force of the gas molecule be less than the force of the liquid on such a scale as a nanometer? Possibly the forces on the bonds of the atoms even?

I concur with IllWill. Could it be surface tension or static pressure that keeps a gas bubble trapped under a liquid? Wouldn't heating the tube just raise the gas pressure higher than the static pressure and break the surface tension?

Using Google Translate;
Tongsu's popular point is the competition between air pressure and hydraulic pressure and molecular surface tension!

I would have thought the phenomenon to be related to capillary action and surface tension of the liquid versus adhesion to the container. I guess I still don't understand the forces involved in capillary action completely.

Hyperbolic. But you make a point.
