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 long capillary tube of radius 0.015 cm is dipped in a liquid, the liquid rises to a height of 15 cm within it. If the contact angle between the liquid and glass to close to 0^@ , the surface tension of the liquid, in milliNewton m^(-1) , is [rho_("liquid") = 900 kgm^(-3), g = 10 ms^(-2)] (give anwer is closet integer)

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 capillary tube is dipped in water to a depth and the water rises to a height h( lt l) in the capillary tube. The lower end of the tube is closed in water by putting a lower over it. The tube is now taken out and the thumb is removed from the lower end and it kept open. The length of liquid column in the tube will be

Figure shows a capillary tube C dipped in a liquid that wets it. The liquid rises to a point A . If we blow air through the horizontal tube H , what will happen to the liquid column in the capillary tube?

It is said that a liquid rises or is depressed in a capillary due to the surface tension. If a liquid neither rises nor depresses in a capillary, can we conclude that the surface tension of the liquid is zero ?

Figure shows a capillary tube of radius r dipped into The atmospheric pressure is P_(0) and the capillary rise of water is h . s is the surface tension for water-glass. Initially, h = 10 cm . If the capillary tube is now incline at 45^@, the length of water rising in the tube will be

The end of a capillary tube is immersed into a liquid. Liquid slowly rises in the tube up to some height. The capillary-fluid system

If a capillary tube is dipped and the liquid levels inside and outside the tube are same. Then the angle of contact is
