Question

A capillary tube is placed vertically in a liquid. If the cohesive force is less than the adhesive force, then

• A. The meniscus will be convex upwards
• B. The liquid will wet the solid
• C. The angle of contact will be obtuse
• D. The liquid will drip in the capillary tube

Answer 1

The correct option is B The liquid will wet the solid

When cohesive forces are less than adhesive forces then we will observe no capillary action and liquid will wet the solid.
