The rise of a liquid inside a capillary tube is dependent on
The rise of a liquid inside a capillary tube is dependent on
Options
- Athe length
- Bthe material
- Cthe inner radius of the tube
- Dthe outer radius
Correct answer
C. the inner radius of the tube
Step-by-step solution
The capillary rise is given by Jurin's law:
where is the surface tension of the liquid, is the angle of contact, is the density of the liquid, is the acceleration due to gravity, and is the inner radius of the capillary tube.
The angle of contact depends on the nature of the liquid and the material of the capillary tube.
Thus, the rise of the liquid depends on the material of the tube and its inner radius. It is independent of the length and the outer radius of the tube.
