When a glass capillary tube is dipped in water, a 1.0 cm rise in the water level is observed at 18 °C. The internal radius of the capillary is ______ cm.
[Given: Surface tension of water at 18 °C = 73.2 dyne cm−1 ; difference in the densities of water and air at 18 °C = 0.996 g cm−3 ; gravitational acceleration constant, g = 980 cm s−2 .
Assume that water completely wets the glass capillary and the interface between the water and the air phase inside the capillary is a hemisphere.] (round off to two decimal places)
