To which point does the capillary rise of a liquid happen against the gravitational force

Answer»

Answer:

The height to which capillary action will take water in a uniform circular tube (PICTURE to right) is LIMITED by surface tension and, of course, gravity. Not only does water tend to STICK together in a drop, it sticks to glass, CLOTH, organic tissues, soil, and, luckily, to the fibers in a paper TOWEL.
