7. First:

8. Next:

9. Finally:

RECOGNIZING CAUSE AND EFFECT:

In the space provided, write the letter of the term or phrase that best completes each statement.

_____ 10. Because water is used to cool power plants, it is returned to its source:

a. cleaner. b. faster

c. hotter d. cooler.

_____ 11. Industry uses water to:

a. manufacture goods. b. dispose of waste.

c. generate power. d. All of the above

Answer 1

1. b. 500,000 L

2. c. 19 percent

3. a. cool power plants

4. d. warmer than the river but clean

5. Three purposes water is used in industry:
- cooling (e.g., of power plants and equipment)
- creating steam to generate energy
- processing/cleaning and running machinery

6. Four goods produced by industry (examples):
- cars
- clothing
- paper
- steel

Sequencing (power plant cooling system):

7. First: Water is drawn from a river or lake and pumped into the plant to cool equipment/condense steam.

8. Next: The water absorbs heat (passes through condensers or cooling towers) and becomes warmer.

9. Finally: The warmed water is returned to the river/lake (usually slightly warmer but not chemically contaminated).

10. c. hotter

11. d. All of the above
