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.

The correct answer is B.

Explanation:

The formation of meniscus occurs between liquids and a proper container. Water-based fluids like sap, honey, and milk have a concave meniscus in glass or other wettable containers. In a non-polar liquid, the cohesive forces are stronger than the adhesive forces, i.e. the particles of the liquid have a greater attraction to each other than to the material of the container.

A classic example of this is the convex meniscus formed by mercury in glass.

The cohesive forces are stronger than the adhesive forces to the glass

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
