Question

please send me the correct answer​

Answer 1

Explanation:

a) mercury liquid

b) when the adhesive force of liquid with the wall of the container is less than the cohesive force of the liquid then we observed the capillary depression. mercury is a liquid that shows capillary depression. Mercury does not wet the walls of the container

c) capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules.the height to which capillary action will take water in a uniform circular tube is limited by surface, tension and, of course, gravity.

d) the capillary rise in inversely proportional to the tube of radius.it can be also applied to the case where the liquid level in the tube decreases below the outer liquid surface; this situation happens when 0=90°
