At 25⁰C, how high will water rise in a glass capillary tube with an inner diameter of 0.63 mm?

Surface tension is the tendency of liquid surfaces at relaxation to reduce into the minimal floor location possible. Surface tensionis what lets items with a better density than water, like razor blades or bugs, to drift on a water surfacewithoutsubmerging them.

Calculate the rise of the water as shown:

\({\rm{h = }}\frac{{{\rm{2Tcos\theta }}}}{{{\rm{\rho rg}}}},\) where T is surface tension of the liquid, \({\rm{\rho }}\) is density of the liquid and \({\rm{\theta }}\) is the angle made by the water on the capillary tube.

\(\begin{aligned}{}{\rm{h = }}\frac{{{\rm{2}}\left( {{\rm{0}}{\rm{.0799\;kg/}}{{\rm{s}}^{\rm{2}}}} \right)}}{{{\rm{(0}}{\rm{.00063\;m)}}\left( {{\rm{1000\;kg/}}{{\rm{m}}^{\rm{3}}}} \right)\left( {{\rm{9}}{\rm{.8\;m/}}{{\rm{s}}^{\rm{2}}}} \right)}}\\\;\;{\rm{ = 0}}{\rm{.025\;m}}\\\;\;{\rm{ = 2}}{\rm{.5\;cm}}{\rm{.}}\end{aligned}\)

Hence, the liquid will rise to a height of \({\rm{2}}{\rm{.5\;cm}}{\rm{.}}\)
