Question

Water spreads out in one large puddle on a sheet of glass (Sheet #1). Water beads up as numerous small spheres on a second sheet of glass (Sheet #2) that has been treated with a mineral solution. What statement explains these observations?

Answer 1

Let assume one of option is - decreasing adhesive forces in between the water molecules and the glass due to mineral solution.

Step-by-step explanation:

Adhesive force is the attraction of two different types of atoms or the molecules of unlike substances. Water and glass molecules are not similar as water is not having charged molecules like the glass molecules. Water molecules are attracted to glass molecules that are charged due to adhesive force.

Treating the glass with mineral solution decreases the adhesive force which leads to forming drops instead of the puddle.

Thus, the correct answer is -decreasing adhesive forces in between the water molecules and the glass due to mineral solution.
