Properties of Water - Video

What shape is water's molecule described as?

• Linear

• Circular

• Tetrahedral

• Outstretched V

What kind of charge does the oxygen in a water molecule have?

• Slightly negative

• Strongly positive

• Slightly positive

• Neutral

What is the role of hydrogen bonds in water's properties?

• They decrease water's boiling point

• They prevent water from freezing

• They enable water's unique behaviors

• They make water non-polar

What property allows water to move up against gravity in plants?

• Condensation

• Cohesion

• Adhesion

• Evaporation

How do water striders move on the surface of water?

• By exploiting surface tension

• By swimming

• By flying

• By walking

Which of the following is NOT a reason why water is a powerful solvent?

• It has high surface tension

• It forms hydrogen bonds

• It is polar

• It can dissolve many molecules

What happens to water when it freezes?

• It contracts and becomes denser

• It expands and becomes less dense

• It remains the same

• It evaporates

What is the specific heat of water described as?

• Variable

• Moderate

• Low

• High

Why is water's high specific heat important for aquatic life?

• It decreases cohesion

• It allows water to freeze faster

• It stabilizes temperature

• It increases evaporation

What effect does evaporative cooling have?

• It warms the environment

• It cools the environment

• It has no effect on temperature

• It increases humidity
