Which property of water allows it to dissolve many substances?

• High density

• Universal solvent

• Low boiling point

• Magnetic property

Compare the arrangement of water molecules in the solid, liquid, and gas states.

Explain why ice floats on water.

• Ice is denser than liquid water

• Ice is less dense than liquid water

• Ice is heavier than water

• Ice is magnetic

Which unique property of water helps regulate Earth's temperature?

• Low specific heat

• High specific heat

• High density

• Low boiling point

A scientist observes that water droplets form on the outside of a cold glass. Using your knowledge of water's properties, explain what is happening and why.

• Water is leaking from the glass

• Water vapor in the air is condensing on the cold surface due to water's ability to change states

• The glass is producing water

• The glass is absorbing water from the table

Given water's unique properties, predict what might happen to aquatic life if water became denser as it froze instead of less dense.

• Aquatic life would thrive more in winter

• Ice would sink, possibly freezing entire bodies of water and harming aquatic life

• There would be no change

• Water would evaporate faster
