Water 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.

• water tends to push up into a dome over a container before it finally spills.

Because of surface tension, you can put things into a full glass of water and...

• the water will immediately spill.

• the water won't spill for quite a while.

• the water will never spill.

• when the water spills, whatever you put in will also spill.

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.

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.

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

Rain drops are spherical in shape because of

• low temperature
• Surface Tension
• Viscosity
• External forces

surface tension of water can be reduced by

• heating

• Adding soap solution

• cooling

• adding salt

Force of attraction between similar molecules is called 

• Cohesive force
• Adhesive force
• Magnetic force
• gravitational force

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

• Adhesion

• Cohesion
