8.6C Adhesion, Cohesion, 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.

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

• Adhesion

• Cohesion

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.

What word describes when water is attracted to other substances?

• cohesion
• adhesion
• capillary action
• surface tension

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

• cohesion
• adhesion
• solution
• polar molecule

Water droplets take a spherical shape (as pictured) because of ____________

• adhesion
• cohesion
• capillary action
• solubility

Water beads up on the surface of a penny because of this property.

• Adhesion
• High Surface Tension
• Universal Solvent
• Changes in Density

Which characteristic of water will allow a paperclip to remain floating on water when the paperclip is gently placed on top of the water?

• adhesion
• surface tension
• solvent properties
• nonpolar

Water's ability to stick to glass is

• adhesion

• cohesion

• surface tention

• capillary action

What is adhesion?

• Water's ability to stick to itself
• Water's ability to stick to other substances
• The strength of the cohesion of all the water molecules combined
• Tape, glue and other adhesives
