MCQ
Consider a liquid contained in a vessel. The liquid solid adhesive force is very weak as compared to the cohesive force in the liquid. The shape of the liquid surface near the solid shall be
  • A
    Horizontal
  • B
    Almost vertical
  • C
    Concave
  • ✓
    Convex
✓

Answer

Correct option: D.
Convex
(d) Cohesive force $>$ Adhesive force, so shape of liquid surface near the solid would be convex.For example mercury surface in glass capillary is convex.
