If surface tension of water is 0.07 N/m the weight of water supported in a capillary tube of radius 0.1 mm is

Water rises a height of 10 cm in a capillary tube. When the same capillary tube is dipped in mercury it falls to a height of 3.4cm. Compare the surface tensions of water and mercury. Assume that the specific gravity of mercury is 13.6, angle of contact of water with glass is 0^(@) and angle of contact of water with glass is 135^(@) .

Surface tension arises from the cohesive force between the surface molecules, Interplay between cohesion and adhension forces make the surface inclined at acute or obtuse angle with the contacting solid surfaces. This causes a capillary rise (or fall) given as, h=(2T cos theta)/( rho g r) where theta = angle of contact, T = surface tension, rho =density of the liquid, g = acceleration due to gravity and r = radius of the capillary tube. If the vessel accelerates up, capillary rise

A liquid rises to a height of 60 mm capillary tube of diameter 0.04 mm. If the density of that liquid is 0.8xx10^(3)Kgm^(-3) , and angle of contact is 20^(@) , find the surface tension of that liquid.

Water rises to a height of 6cm in a capillary tube. If T = 7.2 xx 10^(-2) Nm^(-1) and g = 10ms^(-2) the radius of the tube is
