WebAug 14, 2024 · Capillary action is the phenomenon in which liquids rise up into a narrow tube called a capillary. It results when cohesive forces , the intermolecular forces in the … WebApr 3, 2024 · Capillary action is a principle that explains why fluids are often drawn up into other substances. This phenomenon is also sometimes described as “capillarity.” A classic example of this action involves a paper towel and a spilled puddle of water: when the towel is dipped into the water, it sucks the water up.
Capillary action is observed in thin layer chromatography, in which a solvent moves vertically up a plate via capillary action. In this case the pores are gaps between very small particles. Capillary action draws ink to the tips of fountain pen nibs from a reservoir or cartridge inside the pen. See more Capillary action (sometimes called capillarity, capillary motion, capillary rise, capillary effect, or wicking) is the process of a liquid flowing in a narrow space without the assistance of, or even in opposition to, any external forces … See more Capillary penetration in porous media shares its dynamic mechanism with flow in hollow tubes, as both processes are resisted by viscous forces.
