Question

applications of Ascent formula​

Answer 1

$\sf{\huge{Ascent\: Formula}}$ :

When a capillary tube of radius r is dipped in a liquid of density p and surface tension ( sigma), the liquid rises or falls through a distance,

h = 2 sigma Cos theta / r p( rho ) g

The ascent formula shows that the height h to which a liquid rises in the capillary tube is

( i ). Inversely proportional to radius.

( ii ). Inversely proportional to density.

( iii ). directly proportional to the surface tension of the liquid.

Hence, the liquid rises more in a narrower tube than in wider tube.
