Question

which example illustrates adhesion?
○ water droplets sticking to a window
○ water forming a large drop
○ water evaporating from a leaf
○ water falling from the sky

Explanation:

Adhesion is the attraction between different substances. Water droplets sticking to a window shows water (a liquid) adhering to the window (a solid surface), which is adhesion. Water forming a large drop is cohesion (attraction between same molecules). Water evaporating is a phase change, and water falling from the sky is precipitation, neither related to adhesion.

Answer:

A. water droplets sticking to a window
