Water beads up on the surface of a penny because of this property.
A
Adhesion
B
High Surface Tension
C
Universal Solvent
D
Changes in Density
Explanation: 

Detailed explanation-1: -The attraction of water molecules to other substances, like soil or glass, is called adhesion. As drops of water are added onto a penny, the adhesive force between the water and the penny keeps the water from falling off. Cohesive forces are strong, but not unbreakable.

Detailed explanation-2: -Water has a high surface tension. This happens because water molecules like to stick together. This property is called cohesion. Water also likes to stick to other things, like the penny.

Detailed explanation-3: -Water is highly cohesive-it is the highest of the non-metallic liquids. Water is sticky and clumps together into drops because of its cohesive properties, but chemistry and electricity are involved at a more detailed level to make this possible.
