Why Meniscus Is Formed?

Why a meniscus occurs
Adhesion is responsible for a meniscus and this has to do in part with water's fairly high surface tension. ... And since water molecules like to stick together, when the molecules touching the glass cling to it, other water molecules cling to the molecules touching the glass, forming the meniscus.

Why lower meniscus is formed?

A meniscus is a curve formed on the upper surface of a liquid inside a container. ... If the molecules in the liquid are more attracted to the sides of the container than to each other, the liquid will stick to the sides of the container. When this happens, the meniscus curve bends down and is called concave.

Why is a meniscus created in a narrow tube?

The meniscus curve on a column of fluid in a capillary tubeThe curvature of the surface at the top of a column of fluid in a narrow tube is caused by the relative strength of the forces responsible for the surface tension of the fluid (cohesive forces) and the adhesive forces to the walls of the container.
