Properties of Water

Front

What is the molecular structure of water?

Back

Water (H2O) consists of two hydrogen atoms covalently bonded to one oxygen atom.

Front

Why can water have no net charge but have slight charges in different parts of the molecule?

Back

The oxygen end is slightly negative and the hydrogen end is slightly positive.

Front

What are attractions between water molecules called?

Back

Hydrogen bonds.

Front

Why does ice float on water?

Back

As water freezes, it expands and its density decreases.

Front

What makes water a polar molecule?

Back

The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.

Front

What two elements make up water?

Back

Hydrogen and oxygen.

Front

What is the significance of hydrogen bonds in water?

Back

Hydrogen bonds are responsible for water's unique properties, such as high surface tension and boiling point.

Front

How does water's high specific heat benefit the environment?

Back

It helps regulate temperature in the environment, allowing for stable climates.

Front

What is cohesion in relation to water?

Back

Cohesion is the attraction between water molecules, which allows for surface tension.

Front

What is adhesion in relation to water?

Back

Adhesion is the attraction between water molecules and other substances, which helps water climb up plant roots.
