Rise of liquid in a capillary tube is due to_________________?
Correct answer: C. Both A. & B.
- A. Cohesion
- B. Adhesion
- C. Both A. & B.
- D. Neither A. nor B.
Explanation
Capillary rise requires adhesion between the liquid and tube wall, while cohesion helps maintain the continuous liquid column. Therefore both forces contribute to the observed rise.
