Question

Define capillary force? in biology​

Answer 1

Answer:

We can define capillary action as a phenomenon where ascension of liquids through a tube or cylinder takes place. This primarily occurs due to adhesive and cohesive forces.

The liquid is drawn upward due to this interaction between the phenomena. Narrower the tube, higher will the liquid rise. If any of the two phenomena’s i.e. that of surface tension and a ratio between cohesion to adhesion increase the rise will also increase. Although, if the density of the liquid increases, the rise of the liquid in the capillary will lessen.

Capillary action is important for moving water (and all of the things that are dissolved in it) around. It is defined as the movement of water within the spaces of a porous material due to the forces of adhesion, cohesion, and surface tension.
