The end of a capillary tube with a radius r is immersed in water. Is mechanical energy conserved when the water rises in the tube? The tube is suficiently long. If not calculate the energy change.

The end of a capillary tube with a radius r is immerseed into water. What ammount of heat will be evolved when the water rises in the tube ? If surface tension of water 'T' density of water = rho . Given (T^(2))/(rhog) = (2)/(pi) .

The end of a capillary tube of radius r is immersed in water of surface tension T and density rho . How much heat will be evolved when water rises in the tube? [Hint: Heat evolved = work done by surface tension - gravitational energy stored in the standing column.]

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

The height of water in a capillary tube os radius 2 cm is 4 cm . What should be the radius of capillary , if the water rises to 8cm in tube ?

If a capillary tube of diameter 0.4 m is dipped vertically into water, then the height to which water rises in the capillary tube will be ,

If a capillary tube made up of silver is dipped in water . It is found that there in no rise or fall of water in the tube . This shows that the angle of contact is

When two capillary tubes A and B are immersed in water , the heights of water columns are found to be in the ratio 2:3 the ratio of the radii of tubes A and B is

A capillary tube of the radius r is immersed in water and water rise in it to a height H. Mass of water in the capillary tube is m. If the capillary of radius 2r is taken and dipped in water, the mass of water that will rise in the capillary tube will be
