Question

which statement about water best illustrates the property of adhesion?
○ water droplet found on a spider web in the morning
○ water molecules in a drop of dew
○ water is necessary for animal respiration
○ water dissolving salt into a solution

Explanation:

Adhesion is the attraction between water molecules and other substances. A water droplet on a spider web shows water adhering to the web (a different substance). Water molecules in dew relate to cohesion (attraction between water molecules). Water for respiration is about its biological role, and dissolving salt is about solubility (polarity), not adhesion.

Answer:

A. water droplet found on a spider web in the morning
