Adhesion Cohesion and Surface Tension

Surface tension is the property of water in which...

• water molecules at the surface tend to stick together.

• water spills easily.

• water tends to be see-through.

tendency of molecules of the same kind to stick to one another

• cohesion
• adhesion
• solution
• polar molecule
