  1. 1. Power is • The amount of energy produced minus the energy used to extract, process and transport the resource. • The rate at which energy is consumed. • The ratio of energy produced ÷ the amount of energy to extract, process and transport • The ability to do work.

  2. Power = Energy Time 1 Watt= 1 Joule /sec.

  3. 2. A measure of the amount of randomness, disorder in a system is called • Enthalpy • Entropy • Net energy yield • Net energy ratio

  4. 3. The Second Law of Thermodynamics explains that in an energy conversion • Entropy increases • Entropy decreases • Energy quality increases • Energy quality decreases • A and D • B and C

  5. 4. A 100 W light bulb that is on for 2000 hours in a year uses how much energy? • 0.05 Watt/hr • 0.05 Watt-hr • 200 Watt/hr • 200 Watt-hr • 2 x 105 Watt/hr • 2 x 105 Watt-hr

  6. Power = Energy Time Energy = Power x Time 100 W x 2000 hours = 2 x 105 Watt-hours (Since Watts and Hours are multiplied the unit is a Watt-hour.) or 200 kWh

  7. 5. Which of the following compounds result in acid rain? • O3 • CH4 • SO2 • NO2 • Mercury • C and D

  8. 6. Which fossil fuel is the main source of sulfur dioxide (SO2)? • Shale oil • Tar sands • Natural gas • Coal

  9. Sulfur dioxide and nitric oxides can both react with water vapor in the atmosphere to produce acid compounds (sulfuric acid and nitric acid). Rain is normally weakly acidic because some of the carbon dioxide in the atmosphere also reacts with water vapor to form carbonic acid. But sulfur dioxide and nitric oxides result in rain with an even lower pH.

  10. 7. Which fossil fuel results in the greatest emission of mercury? • Shale oil • Tar sands • Coal • Methane Hydrates

  11. 8. Which fossil fuel has the highest net energy ratio and the lowest carbon dioxide emissions per unit of energy provided? • Coal • Shale oil • Natural gas • Tar sands

  12. 9. The main compound in natural gas is • Methane • Butane • Propane • Ethanol

  13. 10. Tertiary oil extraction • Occurs when oil gushes from a well • Is when steam or carbon dioxide must be pumped into a well to extract the oil • Has a lower net energy yield than primary oil extraction • A and C • B and C

  14. 11. The process of refining crude oil into its different components (gas, diesel, petrochemicals etc.) is based on the differing _____ of these components. • densities • boiling points • reactivity with O2 • solubility

  15. Lowest Boiling Point Gases Gasoline Aviation fuel Heating oil Diesel oil Naphtha Grease and wax Heated crude oil Asphalt Furnace Highest Boiling Point

  16. 12. An organization of 13 of the world’s biggest producers of oil is called • IPCC • PON • OPEC • BPEX

  17. 13. A country that has recently become a major producer of oil due to new technology and is not part of OPEC is • Indonesia • Libya • Venezuela • Canada

  18. 14. The material that is separated from a mineral resource is called • The overburden • The spoil • Tailings

  19. 15. A dispersant is a • form of bioremediation that uses a microbe to break down the fossil fuel • is a chemical agent that can break downthe fossil fuel • is a substance that physically breaks apartthe fossil fuel into smaller droplets but does NOT chemically break down the fossil fuel

  20. Dispersants – disperse (spread out) the substances. They do not chemically break down the substance. Increased surface area may allow any microbes present that can break down the oil to be able to do so more quickly. Term to know: Bioremediation = using a living thing to remedy (help solve) an environmental problem. If microbes that could break down oil were utilized this would be bioremediation.

  21. 16. An environmental problem with tar sands and oil shale compared with traditional oil is • Increased demand for water • Increased land disruption • Lower net energy yield • A and C • B and C • A, B and C

  22. 17. The new increases in the CAFE standards will require that by 2025 • All passenger cars sold will have a fuel efficiency of at least 54.5 mpg. • The average fuel efficiency for the passenger cars sold by each car maker must be 54.5 mpg.

  23. 18. Which of the following statements is correct. (k = kilo, M = mega) • 106Wh= 1 MWh • 103 Wh= 1 MWh • 103kWh = 1 MWh • 103MWh = 1 kWh • A and C • B and D

  24. 19. A disadvantage with natural gas is • It is difficult to transport • Leaking pipelines could result in the release of methane- a strong greenhouse gas • It has a lower net energy yield • A and B • A, B and C

  25. B • B • E • F • F • D • C • C • A • E • B • C • D • C • C • F • B • E • D
