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

The lower end of a capillary tube of radius r is placed vertically in water. Then with the rise of water in the capillary through height 'h'. heat evolved is : (Take d= density of water )

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

One end of a capillary tube of radius r is immersed vertically in water and the mass of water rises in the capillary tube is 5gm. if one end of another capillary tube of radius 2r is immersed vertically in water, what will be the mass of water that will rise in it?

A glass capillary tube of radius r is placed vertically touching the surface of water. The water rises to height h in capillary tube. If now the tube is dipped into water till only h/2 length of it is outside the water surface the , radius of curvature of the meniscus of water in capillary tube will be,
