Adhesion, Cohesion & Surface Tension

Front

What is COHESION?

Back

Cohesion is the attraction between water molecules, causing them to stick together.

Front

What are the attractions between water molecules called?

Back

Hydrogen bonds.

Front

What allows a paperclip to float on water?

Back

Surface tension allows the paperclip to remain floating on water.

Front

Which end of the water molecule has a slightly positive charge?

Back

The hydrogen end of the water molecule has a slightly positive charge.

Front

What is a molecule in which opposite ends have opposite electric charges?

Back

A polar molecule.

Front

What is ADHESION?

Back

Adhesion is the attraction between water molecules and other substances.

Front

What is SURFACE TENSION?

Back

Surface tension is the property of the surface of a liquid that allows it to resist an external force.

Front

How does temperature affect surface tension?

Back

As temperature increases, surface tension decreases.

Front

What is an example of a polar molecule?

Back

Water (H2O) is an example of a polar molecule.

Front

What is the role of hydrogen bonds in water?

Back

Hydrogen bonds give water its unique properties, such as high surface tension and cohesion.
