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

E. The strong cohesion between water molecules

Explanation:

Water is a very special molecule because of its hydrogen bonds. And, because of these hydrogen bonds, water has many properties that make it unique compared to other substances.

One such property is that it is cohesive, which means water molecules are attracted to each other. This is due to the polar bonds and hydrogen bonds that water molecules have. Because of the polar and hydrogen bonds, the molecules attract each other and stick together, creating that bead-like phenomenon that the student sees on the table.

Thus, the answer is E.
