8/16 - Cohesion, Adhesion and Surface Tension

Attraction between water molecules is known as (a)   .

• Buffer
• Adhesion
• Hydrogen Bond
• Cohesion

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.

Refer to the picture of water sticking to a leaf; this is occurring because of:

• Adhesion

• Cohesion

• Compound

• Surface Tension

Describe COHESION.

• Water molecules attracted to other substances.

• Water molecules climbing upwards against the force of gravity.

• Water molecules dissolving many substances because of its polarity.

• Water molecules attracted to other water molecules.
