Answered by gunbir111

Answer:

Capillary action (sometimes capillarity, capillary motion, capillary effect, or wicking) is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. ... It occurs because of intermolecular forces between the liquid and surrounding solid surfaces

❥The phenomena of rise and fall of liquid in a capillary tube us known as Capillary action or effect.

$\huge{\mathfrak{\underline{\overline{\mid{Ascent \: Formula:-}\mid}}}}$

Let T :- Surface tension of liquid.

R:- Radiutof curvature of concave surface.

❥It is experimentally found that below concave surface is less than 2T/R from pressure just above it. In order to compensate this pressure difference liquid rises inside capillary tube.

H= 2T cos theta/r×rho×g
