Understand Water's Unique Characteristics

Front

What property of water allows it to form hydrogen bonds?

Back

Its polar nature.

Front

What type of bond is formed when a hydrogen and an oxygen participate, causing the oxygen to pull shared electrons closer?

Back

Covalent bond.

Front

What is the effect of cohesion and adhesion working together in plants?

Back

They allow water molecules to be pulled up a plant's vascular tissue.

Front

Why does water resist temperature change?

Back

Because of hydrogen bonding.

Front

Which property allows water striders to walk on water?

Back

Surface tension.

Front

Define cohesion in the context of water.

Back

Cohesion is the attraction between water molecules due to hydrogen bonding.

Front

Define adhesion in the context of water.

Back

Adhesion is the attraction between water molecules and other substances.

Front

What is surface tension?

Back

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

Front

Explain why ice floats on water.

Back

Ice is less dense than liquid water due to the arrangement of hydrogen bonds.

Front

What is the significance of water's high specific heat?

Back

It helps regulate temperature in the environment and organisms.
