    "The curved surface of a liquid in a narrow tube or container, formed by the interplay of cohesive and adhesive forces between the liquid and the container walls. In a mercury barometer, the meniscus is convex due to mercury's strong cohesive forces. This curvature must be accounted for when reading liquid levels in meteorological instruments.",
