The rise of a liquid in a capillary tube does not depend upon:

1) Density of the tube
2) Gravitational acceleration
3) Surface tension
4) Radius of the tube

Answer :

Final answer:

The rise of a liquid in a capillary tube does not depend upon the (1.) density of the tube. Factors like surface tension, gravitational acceleration, and the radius of the tube govern capillary action, while the tube material's density is irrelevant.

Explanation:

The rise of a liquid in a capillary tube depends on several factors including the surface tension of the liquid, the inside radius of the tube, the density of the liquid, and the gravitational acceleration. The one factor that the rise does not depend on is the density of the tube material itself. When a capillary tube with a small diameter is inserted into a liquid that wets the surface, the liquid will rise inside the tube. Because the forces involved are based on the interaction between the liquid and the tube at their interface, the density of the tube material does not play a role in this capillary action.

According to the given references and theory of capillary action, other factors such as the contact angle between the liquid and the tube also influence the height to which the liquid will rise. However, the specific question of what the rise does not depend on can clearly be singled out as the density of the tube. The height of capillary rise is indeed affected by the surface tension driving the liquid upwards, and the downward force of gravity which relates to the radius of the tube and density of the liquid (but not the tube).
