Question

A liquid is kept in a glass vessel. If the liquid solid adhesive force between the liquid and the vessel is very weak as compared to the cohesive force in the liquid, then the shape of the liquid surface near the solid should be

• A. Concave
• B. Convex
• C. Horizontal
• D. Almost vertical

Answer 1

The correct option is B Convex

If cohesive forces are stronger than adhesive force then we can observe obtuse angle of contact leading to convex meniscus of liquid near to the solid.
