Answer :
Final answer:
(2) atmospheric pressure
The rise of liquid in a capillary tube is independent of atmospheric pressure, whereas it depends on factors including surface tension, contact angle, radius of the capillary, and liquid density.
Explanation:
The quantity on which the rise of liquid in a capillary tube does not depend is atmospheric pressure. The height to which a liquid rises in a capillary tube is determined by the surface tension of the liquid (T), the contact angle between the liquid and the tube (θ), the radius of the capillary tube (r), the density of the liquid (p), and the acceleration due to gravity (g, 9.8 m/s²). Factors such as the density of the liquid, the radius of the capillary, and the angle of contact directly contribute to the capillary rise, whereas atmospheric pressure is notably absent from the key determinants.
