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 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^(@) .
