A liquid rises to a height of 34.0 mm in a glass capillary. A second capillary with twice the diameter of the first is then test. How high will the liquid rise?
Homework Answers
SOlution :-
given data :-
intial height h1 = 34 mm
diameter d1 = D=2r = r1 = D/2
fianl height h2 = ?
final diameter d2 = 2D = 4r
formula : from the jurin's law hr=constant
h1r1 = h2r2 or h1d1 = h2d2 note :- D =2r
substitue in it 34 x D = 2D x h2
height rises in second column is
h2 = 17 mm

4) When a glass capillary is dipped into water, the liquid will rise inside of the tube. This phenomenon is called capillary action. The picture on the right shows a glass capillary dipping into a beaker filled with water. What will happen to the water in the capillary if you pull the tube slowly out of the water? Please explain. Would the capillary action change if the capillary was made out of polypropylene, a hydrocarbon-like polymer? Please explain.
