Explanation:
Capillary rise is the phenomenon of the rise of a liquid in a narrow tube due to the forces of adhesion and cohesion. The rise of liquid is attributed to the surface tension property of the fluid.

Surface Tension:
Surface tension is the property of a liquid that arises due to the cohesive forces between the molecules at the surface of the liquid. The surface molecules of the liquid experience a net inward force due to the unbalanced forces of attraction from the molecules below the surface. This results in a tendency of the liquid to minimize its surface area and form a spherical shape.

Capillary Action:
Capillary action is the result of the combination of forces of adhesion and cohesion. Adhesion is the force of attraction between the molecules of the liquid and the solid surface of the tube. Cohesion is the force of attraction between the molecules of the liquid itself.

Capillary Rise:
When a small diameter tube is dipped into a liquid, the liquid rises up the tube until the weight of the liquid column is balanced by the surface tension and adhesive forces of the liquid to the tube. The height of the liquid column is directly proportional to the surface tension of the liquid and inversely proportional to the diameter of the tube.

Conclusion:
In conclusion, capillary rise is a phenomenon attributed to the surface tension property of a fluid. The surface tension of the liquid causes it to rise up the narrow tube due to the forces of adhesion and cohesion. Capillary rise has many applications in various fields, including civil engineering.
