Question

an unknown liquid in a glass tube forms a meniscus, similar to the one shown below. from this observation, which of the following statements can be made? meniscus of liquid in glass tube - liquid curves up towards glass glass and liquid form hydrogen bonds adhesive forces between liquid and glass are stronger than cohesive forces within the liquid adhesive forces between liquid and glass are weaker than cohesive forces within the liquid hydrogen bonding dominates the cohesive forces within the liquid dispersion forces dominate the cohesive forces within the liquid

Explanation:

When a liquid in a glass - tube forms a meniscus that curves up towards the glass, it indicates that the adhesive forces between the liquid and the glass are stronger than the cohesive forces within the liquid. Adhesive forces are the attractions between different substances (liquid - glass), and cohesive forces are the attractions between like - substances (molecules within the liquid). A concave meniscus (curving up towards the glass) is a result of stronger adhesive forces pulling the liquid up the sides of the tube.

Answer:

Adhesive forces between liquid and glass are stronger than cohesive forces within the liquid
