A glass capillary sealed at the upper end is of length 0.11 m and internal diameter 2xx10^(5) m. The tube is immersed vertically into a liquid of surface tension 5.06xx10^(-2)N//m . To what length the capillary has to be immersed so that the liquid level inside and outside the capillary becomes the same. What will happen to water level inside the capillary if the seal is now broken?

The liquid in the capillary tube will rise if the angle of contact is

When a capillary tube is dipped in a liquid, the liquid rises to a height H in the tube. The free liquid surface inside the tube is hemispherical in shape. The tube is now pushed down sothat the height of the tube outside the liquid is less than H. Then the

When a capillary tube is dipped into a liquid, the liquid neither rises nor falls in the capillary.

When a capillary tube is dipped in a liquid, it rises in the tube to a height h above the outside level . What would happen it the tube is dipped such that its length outside the liquid is less then h? Explain your answer briefly.

A liquid rises in a capillary tube when the angle of contact is:

A student writes the equation for the capillary rise of a liquid in a tube as h=(rhog)/(2Tcos theta) , where r is the radius of the capillary tube, rho is the density of liquid, T is the surface tension and theta is the angle of contact. Check the correctness of the equation using dimensional analysis?
