Question

hey guys it's physics, PHYSICS EXPERTS PLLSSS HELP ME WILL MARK U AS BRAINLIST ​

Answer 1

Answer:

a) Mercury

Explanation:

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

c) when the adhesive force is greater than cohesive force the capillary rise of a liquid happen against the gravitational force.

d) The capillary rise is inversely proportional to the tube radius.it can be also applied to the case where the liquid level in the tube decreases below the outer liquid surface,thus situation happens when( teeta equal to 90 degree).
