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
- AHorizontal
- BAlmost vertical
- CConcave
- ✓Convex
✓
Answer
Correct option: D.
Convex
d
(d) Cohesive force $>$ Adhesive force, so shape of liquid surface near the solid would be 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.
