Question

Explain why different liquids do not reach the same height in capillary tubes of the same diameter. Please choose the best explanation. Polar molecules climb higher than nonpolar molecules. The larger the dipole moment, the higher the liquid rises. Cohesive forces stronger than adhesive forces reduce the height of the liquid in the capillary tube, whereas adhesive forces stronger than cohesive forces increase the height of the liquid. The height of the liquids in the capillary tubes depends on the density of the liquid. Different liquids have different intermolecular forces. The stronger the intermolecular forces within the liquid, the higher the liquid rises in the capillary tube.

Explanation / Answer

The height (h) of a liquid column is given by:

h=2T/rg

where T is the surface tension, is the density of liquid, g is the acceleration due to gravity, and r is radius of the tube.

AS density increases hieght reduces.
