A liquid rises in a capillary tube when the angle of contact is:

If a liquid does not rise or fall in a capillary tube , then its angle of contact is

The radius of the bore of a capillary tube is r and the angle of contact of the liquid is theta . When the tube is dipped in the liquid , the radius of curvature of the meniscus of liquid rising in the tube is

Liquid rises to a height of 2 cm in a capillary tube and the angle of contact between the solid and the liquid is zero. If the tube is depressed more now so that top of capillary is only 1 cm above the liquid, then the apparent angle of contact between the solid and the liquid is

What is capillarity? Derive an expression for the height to which the liquid rise in capillary tube of r with angle of contact theta . Give two examples of capillarity from daily life.

For liquid to rise in a capillary tube , the angle of contact should be

When liquid does not rises in a capillary tube , the angle of contact is
