GHF: Unit 4: Lesson 1 Water Properties

Two hydrogen atoms bonded to one oxygen atom at an angle

Three hydrogen atoms bonded to one oxygen atom in a straight line

One hydrogen atom bonded to two oxygen atoms in a triangle

Two oxygen atoms bonded to one hydrogen atom at an angle

Cohesion

Adhesion

Surface tension

Polarity

Water's heat capacity is low, so it heats up quickly.

Water can absorb a lot of heat with only a small change in temperature.

Hydrogen bonds in water do not require energy to break.

Water's heat capacity is the same as all other liquids.

Cohesion

High heat capacity

Density of ice

All of the above

96.5%

55%

30.6%

3.5%

Depth

Latitude

Runoff

All of the above

Density increases

Density decreases

Density stays the same

Density fluctuates unpredictably

Hydrogen ions (H+) increase the pH of a solution.

Hydrogen ions (H+) decrease the pH of a solution.

Hydrogen ions (H+) make the solution neutral.

Hydrogen ions (H+) have no effect on pH.

To regulate the pH of ocean water

To increase the amount of carbon dioxide in the ocean

To remove all hydrogen ions from the water

To convert oxygen into carbon dioxide
