Properties of Water Case Study

What is one of the most notable characteristics of water?

• Its dipolar nature

• Its high viscosity

• Its low boiling point

• Its colorless appearance

As salinity increases, what happens to water's density?

• Increases density

• Decreases density

• No effect on density

• Makes water evaporate faster

What happens to the density of water when it freezes?

• Decreases

• Increases

• Remains the same

• Becomes zero

At what temperature does water reach its maximum density?

• 4 degrees Celsius

• 0 degrees Celsius

• 10 degrees Celsius

• -4 degrees Celsius

Why does ice float on water?

• Because its density is lower than liquid water

• Because it is lighter than air

• Because of surface tension

• Because of its color

What role does floating ice in polar regions play?

• Regulating Earth's climate

• Increasing ocean salinity

• Decreasing water temperature

• Supporting marine life
