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 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 so that the height of the tube outside the liquid is less than h . Then

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 ?

When a capillary tube of radius r is immersed in a liquid of density rho, the liquid rises to a height h in it. If m is the mass of the liquid in the capillary tube, find the potential energy of this mass of the liquid in the tube.

A capillary is dipped into a liquid which does not wet , the liquid level

A capillary tube of radius r is immersed in water and water rises to a height of h mass of water in the capillary tube is 5xx10^(-3) kg the same capillary tube is now immersed in a liquid whose surface tension in sqrt(2) times the surface tension of water. The angle of contact between the capillary tu8be and this liquid is 45^(@) the mass of liquid which rises into the capillary tube now is (in kg)

A liquid rises to a height of 3.6 cm in capillary tube of radius r . If the radius of the capillary tube is made 0.75 r, then the height to which the liquid will rise in the capillary tube is

Assertion If angle of contact is 0^(@) , then liquid will neither rise nor fall in a capillary. Reason : When angle of contact is 0^(@) , surface is neither convex nor concave inside the capillary. It is flat.
