Water Properties

Front

Which property of water enables it to move from the roots to the leaves of plants?

Back

Water exhibits cohesive behavior.

Front

Most of water's unique features (such as its great ability to dissolve other substances, its high boiling point, and its great surface tension) result from the fact that:

• hydrogen is the only element without any neutrons
• oxygen attracts electrons more than hydrogen does
• hydrogen attract electrons more than oxygen
• hydrogen and oxygen share electrons equally

Back

oxygen attracts electrons more than hydrogen does

Front

What property of water accounts for moderate temperatures around large bodies of water?

Back

Water has the ability to absorb, store, and release large amounts of thermal energy.

Front

What characteristic must a molecule have for it to form a solution in water?

Back

It must be at least slightly polar to be able to react with the polar water molecules.

Front

Which property of water molecules gives water its high surface tension?

Back

Water molecules attract other water molecules.

Front

Why does ice float on water when a lake freezes?

Back

Ice is less dense than liquid water, so it floats.

Front

Why will salt form a solution with water, but sand will not?

Back

Salt is pulled apart into two ions by the polar water molecules, and sand is not.

Front

When the oxygen atom in one water molecule is close to a hydrogen atom in another water molecule, what is most likely to happen?

Back

The water molecules will draw toward each other

Front

What role does water play in keeping temperatures in Florida from fluctuating dramatically?

Back

Bodies of water store heat during the day and release it at night

Front

Which property of water molecules allows them to cling together?

Back

Water molecules are polar molecules
