When a nonpolar liquid displays a convex meniscus,which of the following explains this behavior?
A)It has a low surface tension,and therefore clings to the glass.
B)The cohesive forces are stronger than the adhesive forces to the glass.
C)The adhesive forces to the glass are stronger than the cohesive forces.
D)The liquid's viscosity is low.
E)None of these.

Question

Quizplus · Accepted Answer

A convex meniscus is observed when cohesive forces among the molecules of the liquid are stronger than the adhesive forces between the liquid and glass. This means that the liquid molecules prefer to stick to each other rather than the glass surface, resulting in a curved shape at the liquid-glass interface.
