13. What factors are important in judging how helpful an energy resource is to us?
First, Casey needs to indicate what S/HE thinks the answers are. Then someone can check her/his thinking.
Good thinking "writeacher"!!! Now Casey, what do you think that # 1,2 and 3 are and then we will go from there!!! Sound Good ?
Hi
Is this a test because there is a lot of questions. I will not give you the answers but I can give you some hints.
thanks but yahoo answers gave me everything i needed
dont always hope there is anwers everywhere do you know IStep they wont let you cheat so try solving it first then let us know what you think!
Casey, I think you're my spirit animal. You're going places, haha!
1. The type of energy transfer described here is conduction. The heat energy from the gas burner is transferred to the pan of water through direct contact and the collision of particles, causing the water to heat up.
2. When you burn wood in a fireplace, you are using a renewable energy resource called biomass. Biomass refers to any organic material, such as wood, that can be used as fuel.
3. The form of energy that is important in making electricity from water power is kinetic energy. Water power, also known as hydroelectric power, harnesses the kinetic energy of flowing or falling water to generate electricity.
4. A hydrocarbon is a compound made up of hydrogen and carbon atoms. They are the main components of fossil fuels such as coal, oil, and natural gas. Hydrocarbons are used as a source of energy due to their high carbon-hydrogen bond energy which can be released through combustion.
5. The byproduct of nuclear energy that has caused concerns is radioactive waste. Nuclear power produces radioactive waste materials that remain hazardous for long periods of time. Safe disposal and management of this waste pose significant challenges and concerns about the potential for accidents or misuse of the waste materials.
6. Two important fuels that come out of the oil refining process are gasoline and diesel. Gasoline is a fuel mainly used for cars and other vehicles, while diesel is commonly used in trucks, buses, and heavy machinery.
7. The chemical element exposed in surface coal mining that can cause environmental problems in nearby bodies of water is sulfur. When coal containing sulfur is exposed to air and water during mining, the sulfur compounds can react with water to form sulfuric acid, which ultimately leads to acid mine drainage that can harm aquatic ecosystems.
8. Natural gas needs to be processed before it can be used as a fuel due to impurities and contaminants present in the raw gas. Processing involves removing moisture, sulfur compounds, trace elements, and other impurities to ensure the gas is safe to use and meets quality standards.
9. While nuclear power is considered clean in terms of greenhouse gas emissions, its adoption is limited due to several reasons. Concerns about radioactive waste disposal and the potential for accidents, high initial costs of building nuclear power plants, public perception and fear of nuclear accidents, and the lack of a centralized nuclear waste disposal solution are among the factors that limit its wider use in the United States.
10. The original source of most energy used on Earth is the Sun. The Sun's energy is harnessed through various means, such as solar power, wind power (which is driven by temperature differences created by the Sun), and indirectly through the fossil fuels that were formed from ancient plants and animals that relied on the Sun for their energy.
11. When a fuel is burned, energy is released in the form of heat, which allows work to be done. This energy is released through a chemical reaction known as combustion, where the fuel combines with oxygen to produce heat, light, and byproducts such as carbon dioxide and water.
12. Renewable energy resources: Biomass, solar, geothermal. Non-renewable energy resources: Coal, natural gas, oil.
13. Factors important in judging how helpful an energy resource is to us include availability, efficiency, cost, environmental impact (including emissions and waste generation), technological feasibility, and sustainability. Evaluating these factors helps us determine the overall benefits and drawbacks of each energy resource in meeting our energy needs efficiently and responsibly.
