The surface tension for pure water in a capillary tube experiment is

The surface tension of pure water is

Calculate the ratio of surface tension of mercury and water if in a capillary tube, mercury is depressed by 3.45 cm and water rises by 9.8 cm in the same tube. The angle of contact for mercury is 140^@ and that for water is 0^@.

The lower end of a capillary tube of radius r is placed vertically in water of density rho , surface tension S. The rice of water in the capillary tube is upto height h, then heat evolved is

In an experiment to determine the surface tension of water by capillary rise, water rises to a height of 0.03m in a capillary tube of diameter 10^-3 m. If the angle of contact is negligibly small, calculate the surface tension of water.

In a surface tension experiment with a capillary tube water rises upto 0.1 m . If the same experiment is repeated in an artificial satellite, which is revolving around the earth , water will rise in the capillary tube upto a height of :

In a surface tension experiment with a capillary tube water rises upto 0.1m . If the same experiment is repeated in an artificial satellite, which is revolving around the earth, water will rise in the capillary tube upto a height of
