- The surface tension of mercury at \( 0^{\circ} \mathrm{C} \) is \( 480.3 \) dynes/cm while the density is 13. \( 60 \mathrm{~g} \) per cc. If it is desired to obtain a fall of \( 10.0 \mathrm{~cm} \) height in capillary what radius of glass capillary rube will have to be used? The angle of contact is \( 140^{\circ} \).
