Capillary action is also essential for the drainage of constantly produced tear fluid from the eye.
Paper towels absorb liquid through capillary action.
Chemists utilize capillary action in thin layer chromatography, in which a solvent moves vertically up a plate via capillary action. Dissolved solutes travel with the solvent at various speeds depending on their polarity.
With some pairs of materials, such as Mercury and glass, the interatomic forces within the liquid exceed those between the solid and the liquid, so a convex meniscus forms and capillary action works in reverse.

What is the attraction between molecules that result in the rise of liquid in small tubes?
capillarity, also known as capillary action.
Explain capillary action?
Capillary action is the motion of water up a thin tube against the flow of gravity as a result of cohesion and adhesion
What factors account for different capillarity in soils?
Texture, for one. Coarser soils (sandy) have much less capillary action than finer soils (clayey).
What are the examples of capillarity?
Capillarity is the movement of liquid without any external forces. The flow of oil in a wick absorption of liquid by paper towel are examples of capillarity.
Derive an expression for expression for rise of liquid in a capillary tube?
deduce an expression for height of a liquid in capillary tube. also write practical applications of capillary action.
What is the definiton of wicking time for liquids in a fabric material?
The ability of a substance to draw another substance into it is known as capillary action, capillarity, capillary motion, or wicking. The time it takes for a liquied to be drawn to a fabric material refers to the wicking time.
What is capillarity phenomena?
The phenomenon in which the level of a liquid raises or drops in a fine capillary tube.
What is the liquid property that allows oil to flow upward in the wick of a lantern?
Liquids are able to travel up narrow tubes or threads because of capillary action. This property causes part of the surface of a liquid to elevate above the rest of the surface when in contact with a solid.
Why does water travel up paper?
ts called capillary action http://hyperphysics.phy-astr.gsu.edu/Hbase/surten2.html#c5
Capillary rise and fall applications in nature?
capillary fall
What is the phenomenon of capillarity?
Capillary action, or capillarity, is a phenomenon where liquid spontaneously rises in a narrow space such as a thin tube, or in porous materials. This effect can cause liquids to flow against the force of gravity. It occurs because of inter-molecular attractive forces between the liquid and solid surrounding surfaces; If the diameter of the tube is sufficiently small, then the combination of surface tension and forces of adhesion between the liquid and container act to lift the liquid
What is it called to move upward through narrow tubes against the force of gravity?
If your referring to liquids going up the narrow tubes, than it can be called "Capillary action" or "capillarity". It occurs when the adhesive intermolecular forces between the liquid and a solid are stronger than the cohesive intermolecular forces withing the liquid. Otherwise, it would be "lift" and that just takes us to physics...
