Answer | Explanation: Ranking the cost of these fuels:
1. Wood
2. Coal
3. Crude oil
4. Uranium
5. Methane
6. Ethane
7. Propane
8. Butane
9. Pentane
10. Methanol
11. Ethanol
12. Isopropanol
13. Hydrogen
Please note that the cost of these fuels can vary depending on factors such as geographical location, availability, and market demand. The ranking provided is a general indication of their relative costs.
Ranking these fuels in terms of public perception:
1. Wood
2. Coal
3. Crude oil
4. Uranium
5. Methane
6. Ethane
7. Propane
8. Butane
9. Pentane
10. Methanol
11. Ethanol
12. Isopropanol
13. Hydrogen
Public perception of fuels can be influenced by factors such as environmental impact, safety concerns, and cultural beliefs. This ranking reflects a general perception, but it can vary among individuals and communities.
Ranking these fuels by CO2 emissions:
1. Coal
2. Crude oil
3. Wood
4. Methane
5. Ethane
6. Propane
7. Butane
8. Pentane
9. Methanol
10. Ethanol
11. Isopropanol
12. Hydrogen
13. Uranium
CO2 emissions vary depending on the fuel's carbon content and combustion process. Coal and crude oil have high carbon content, resulting in significant CO2 emissions. Wood releases CO2 when burned, but it is considered renewable. Methane, ethane, and other hydrocarbons emit less CO2 compared to coal and crude oil. Methanol, ethanol, isopropanol, and hydrogen emit relatively lower amounts of CO2. Uranium is not a fossil fuel, so it does not produce CO2 when used for nuclear energy generation.
Please note that while this ranking provides a general indication of CO2 emissions, other greenhouse gases and environmental impacts should also be considered when evaluating the overall environmental footprint of different fuels.
