Study Guide Material (Stacey’s Guide) :

1) What is meant by “specific heat?” What is “heat capacity” and why is this property

of water so important for life on Earth?

2) Know the difference between cohesion, surface tension and viscosity, and how they

apply to water.

3) Define “density.” How does the density of water vary with changes in pressure and

temperature? How does the density of water compare to other common substances?

4) At approximately what temperature does liquid water reach its maximum density?

5) Why does ice float?

6) Why is liquid water an excellent “solvent?”

7) Why are the oceans so salty?

8) What are the effects of dissolving salt in water? What interesting effect does this

have on the freezing of sea water?

9) What is the approximate freezing point of sea water?
