Capillarity

[Sarah]

The peculiar action by which the surface of a liquid, where itis in contact with a solid (as in a capillary tube), is elevated ordepressed; capillary attraction.

[Rihanna]

the force that causes liquid to rise in a tube or other narrow space against the force of gravity

[Kai]

The tendency of a liquid in a capillary tube or absorbent material to rise or fall as a result of surface tension.

[Gornwexy 0]

a phenomenon associated with surface tension and resulting in the elevation or depression of liquids in capillaries

[GrompelFem]

The interaction between the surfaces of a solid and liquid in contact that distorts the normal geometry of the liquid surface; especially the rise or fall of a liquid in a fine tube.

[rekha patel]

Capillarity, also known as capillary action, is a physical phenomenon where liquid flows in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. This movement occurs due to the cohesive and adhesive forces between the liquid and the surface of the tube. The process is responsible for various natural and biological processes including the movement of water within the stems of plants and the circulation of blood in tiny blood vessels in humans.

[LeeTot 0]

the quality or condition of being capillary

[Lanell]

The action by which the surface of a liquid where it contacts a solid is elevated or depressed, because of the relative attraction of the molecules of the liquid for each other and for those of the solid. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)

The reaction between liquid surfaces of different kinds or between liquid and solid surfaces due to surface tension. Its phenomena are greatly modified by electric charging, which alters the surface tension. Capillarity is the cause of solutions creeping, as it is termed. Thus in gravity batteries a crust of zinc sulphate often formed over the edge of the jar due to the solution creeping and evaporating. As a liquid withdraws from a surface which it does not wet, creeping as above is prevented by coating the edge with paraffin wax, something which water does not moisten. It also causes the liquids of a battery cell to reach the connections and injure them by oxidation. The solutions creep up in the pores of the carbons of a battery and oxidize the clamps. To give good connections a disc of platinum or of lead is used for the contact as not being attacked. Another way is to dip the upper ends of the dry and warm carbons into melted paraffin wax, or to apply the wax to the hot carbons at the top, and melt it in with a hot iron.
