1. Ch. 13 Energy Resources
Study Guide

2. 1.) List and explain the 3 ways heat is transferred.
Conduction-
Heat transferred from one object to another by touch
Convection-
Heat transferred from one object to another by the air or a fluid
Radiation-
Heat transfer from the sun to an object by waves

3. 2.) How is mechanical energy converted into heat?
Water is heated to produce steam
When the water boils it increases pressure
Pressure causes a turbine to spin
The turbine spinning generates electricity

4. 3.) What energy resources are used to generate electricity in the United States? List at least 3.
Fossil fuels
Hydroelectric
Nuclear
Geothermal
Wind

5. 4.) What are the major energy sources used to produce electricity in Washington?
Hydroelectric
Nuclear
Wind

6. 5.) What is the difference between electric power and electric energy?
watt
Watt-hour
Electric Power
Electric Energy
Amount of work electricity can do
Rate electricity does work

7. 6.) How is electric power generated?
Steam turbines
Burning Fossil Fuels- boiler
Nuclear Energy- reactor
Hydroelectric Power- flowing water

8. 7. ) Draw and label a picture of the pH scale
7.) Draw and label a picture of the pH scale. Include: acid, base, neutral, numbers, colors.
acid
NEUTRAL
base

9. 8.) Use a double bubble map to compare and contrast acids and bases.
0-6.9
8-14
red
blue
Acid
pH scale
Base H+
OH -
If too strong, bad for the environment

10. 9.) What are the environmental impacts of using coal?
Burning coal increases CO2 ,NO2 ,and SO2in the air
Large amounts of these gases in the air leads to acid rain
Acid rain leads to changing the pH of the environment: soil, water
Kills fish, insects, plants, plankton

11. Large number of coal-fueled electric power plants
10.) Why is acid raid more harmful in the eastern United States than in other parts of the US?
Large number of coal-fueled electric power plants
Wind blows pollution to the east
bringing the acids where large amounts of rain occurs
Type of rock and soil
Mostly granite so soil doesn’t neutralize the acid rain

12. 11.) What are the positive and negative effects of energy use on communities?
Air quality
Acid rain
Global warming
Ground-water contamination
Maintain a high quality of life
Provide employment

13. 12.) Do you think our society has a big or small dependence on petroleum? Explain.
Very big we consume 18,311,000 barrels of petroleum per day
Has had the greatest impact of any other fuel
No source of energy has ever become so dominant

14. We consume more and more each year
13.) Think back to the graphs you made about US and foreign oil, what is happening to the amount we use each year?
We consume more and more each year

15. 14.) How can the use of sun and wind reduce the use of nonrenewable energy resources?
If the use of wind and solar energy increases then the demand for fossil fuels will decrease.
The cost for wind power is competitive with the price of power produced by coal-fired plants
It is predicted that as of 2005 it will cost less for wind-energy than coal-energy

16. 15.) How does solar heating work?
Solar energy is collected in a box with a black back
Pipes run under the back and water is warmed in the pipes and then stored in a tank

17. 16.) Could wind energy be used in Washington? Why or why not?

18. 17. ) Compare and contrast any 2 energy resources that were presented
17.) Compare and contrast any 2 energy resources that were presented. Include: pros and cons, renewable/nonrenewable, future use, statistics, environmental impacts.
