2. Compare the heights to which water and carbon terachloride will rise as a result of capillary action in a tube with internal diameter of 0.1mm. At 20C the carbon tetrachloride will rise as a result of censions of water and carbon tetrachloride, respectively, are 0.0727 and 0.0268N/m, and their densities are 0.998 and 1.595g/mL.G=9.81m/s2 4. What pressure in bars is required to prevent water from rising in a 101cm diameter capillary at 25C ? roo =71 mN/m
