Question

write the Convex meniscus - obtuse angle of contact​

Answer 1

$\huge\bf{\underline{\underline{Answer : -}}}$

the obtuse angle of contact between a liquid and a solid (e.g., mercury in a glass bottle). Consider a molecule such as A on the surface of the liquid near the wall of the container. The molecule experiences both cohesive as well as adhesive forces. In this case also, the net adhesive force ( AP ) acting on the molecule A is horizontal since the wall is vertical. Magnitude of cohesive force is so large that the net force ( AR ) is directed inside the liquid
