Question

What happens to water molecules on a smooth surface due to cohesion?
They dissolve
They form beads
They change color
They form a solid layer

Answer 1

Water molecules on a smooth surface exhibit cohesion, which causes them to form beads. This phenomenon is due to the cohesive forces between the water molecules, which are stronger than the adhesive forces between the water molecules and the surface. As a result, water tends to minimize its surface area, leading to the formation of droplets or beads instead of spreading out evenly.
