Read each question carefully and answer to the best of your ability. This worksheet will test your knowledge of the unique properties of water.
1. Which property of water allows insects to walk on the surface of a pond?
Adhesion
Cohesion
Surface tension
High specific heat
2. Water is known as the 'universal solvent' because it can dissolve many substances. This is primarily due to its:
Low density
Neutral pH
Polarity
High boiling point
1. The attraction between water molecules is called , while the attraction between water molecules and other substances is called .
2. Water has a high , meaning it takes a lot of energy to raise its temperature. This helps moderate Earth's climate.
3. Unlike most substances, solid water (ice) is dense than liquid water, which is why ice floats.
1. Water molecules are polar because oxygen attracts electrons more strongly than hydrogen.
True
False
2. Capillary action is a result of both cohesion and adhesion working together.
True
False
1. Explain how the polarity of a water molecule contributes to its ability to dissolve many substances.
2. Describe why the high specific heat of water is important for living organisms.
