Question

After spraying water on a waxed surface, a student notices that the water beads up to form many individual drops rather than being spread out evenly across the surface. What property of water causes it to bead up like this? A. the high boiling point of water B. the strong adhesion to other substances C. the high density of liquid water D. the ability to dissolve many other substances E. the strong cohesion between water molecules

Answer 1

E. the strong cohesion between water molecules

Answer 2

The best answer would be:

E. The strong cohesion between water molecules.

Cohesion is the strong attraction between molecules of the same kind. Water has this property because of hydrogen. Hydrogen form strong bonds with each other which keep water molecules intact. When sprayed on a waxed surface they tend to bead because hydrogen bonds are more attracted to themselves, rather than the wax surface.
