Properties of Water Questions
1. Draw a diagram of a water molecule
2. Explain why the bonds within ONE molecule are said to be polar
covalent.
3. What is meant by “polarity”?
4. Draw a diagram showing four other water molecules and how the
hydrogen bonds between them
5. Define cohesion and explain how the chemical bonds of water
give it its cohesive properties.
6. Define adhesion and explain how the chemical bonds of water
give it its adhesive properties.
7. Give an example of how cohesion and adhesion are used in
nature.
8. Define surface tension and explain how it is related to surface
tension.
9. What is meant by the term “specific heat”?
10. What is the relationship between the hydrogen bonds formed by
water molecules and the high specific heat of water?
11. What is the relevance of water’s high specific heat to life on
earth?
12. What is heat of vaporization?
13. How does water’s high heat of vaporization help moderate
Earth’s climate?
14. What is the difference between frozen water and liquid water, in
terms of the molecular movement?
15. Why is ice less dense than water?
16. Why is the fact that ice floats instead of sinks an important factor
in the fitness of the environment?
17. Explain why water is an excellent solvent?
As a review, make a chart with three columns. In the first column, list the
following terms: cohesion, adhesion, surface tension, heat capacity,
boiling point, freezing point, cooling effect of evaporation. In the second
column, explain the property. In the last column state the significance of
the property to living organisms.
