Vedclass · Answer

(A) convex meniscus occurs when the cohesive forces between liquid molecules are stronger than the adhesive forces between the liquid and the container wall.This typically happens when mercury is placed in a glass capillary tube.In a convex meniscus,the angle of contact $	heta$ is defined as the angle between the tangent to the liquid surface and the solid surface,measured inside the liquid.For a convex meniscus,this angle of contact is always greater than $90^{\circ}$.

The liquid meniscus in a capillary tube will be convex,if the angle of contact is
