C1.4.3 Hydrocarbon fuels Additional guidance: a) Most fuels, including coal, contain carbon and/or hydrogen and may also contain some sulfur. The gases released into the atmosphere when a fuel burns may include carbon dioxide, water (vapour), carbon monoxide, sulfur dioxide and oxides of nitrogen. Solid particles (particulates) may also be released. Candidates should be able to relate products of combustion to the elements present in compounds in the fuel and to the extent of combustion (whether complete or partial). No details of how the oxides of nitrogen are formed are required, other than the fact that they are formed at high temperatures.
Fossil fuels like the substance sulfur dioxide products are burnt to heat water under pressure , making them steam. This high pressure steam is used to spin the turbine generators which make electricity although this method is not really used anymore now. 5.) What are the potential hazards for using this resource? The potential hazards for using sulfur dioxide is it can affect our environment, plants, animals, the air that we breathe, our water resources and our planet.
Alcoholic Fermentation Lab Cylie Couch 11-9-12 Introduction: As humans, we consume a lot of energy. There are many effective ways of producing energy, such as by nonrenewable resources like fossil fuels. There are other natural alternative sources of energy as well, which include wind, solar, and ethanol. We need these renewable resources, because the non-reusable ones are getting used at an uncontrollable rate. One way we can make renewable resources is by the alcoholic fermentation of ethanol.
If an ideal pH level is 7 than the carbon was able to take our acidic water and make it more neutral. Coal works as a pH balancer for the earth’s soil and helps to filter out water as it passes through. The pH in the soil has a major impact on the nutrients that come from that soil. The more nutrients that are produced the better ecosystem will function. 4.
(Transition) Body I. Fossil fuel and the alternatives A. Fossil Fuels 1. Merriam-Webster dictionary defines fossil fuel as : A fuel (such as coal, oil, or natural gas) that is formed in the earth from dead plants or animals” B. Hydrogen 1. One of the most abundant elements found on earth. But rarely found by its self. It is most commonly refined from water C. Ethanol 1.
Some of the dissolved carbon dioxide remains in the water, the warmer the water the less carbon dioxide remains in the water. Some carbon dioxide is used by algae and phytoplankton through the process of photosynthesis. In the natural carbon cycle, there are two main processes which occur: * Photosynthesis = plants use carbon dioxide and produce oxygen. * Metabolism = oxygen is used and carbon dioxide is a product Humans impact the carbon cycle during the combustion of any type of fossil fuel, which may include oil, coal, or natural gas. Fossil Fuels were formed very long ago from plant or animal remains that were buried, compressed, and transformed into oil, coal, or natural gas.
Methane is a more active green house gas than CO2 but is less abundant in the atmosphere. Nitrous Oxide is a strong greenhouse gas produced by soil cultivation with the use of commercial and organic fertilizers and fossil fuel combustion. Finally Chlorofluorocarbons are synthetic compounds of industrial origin that are used for the destruction of the ozone
It also releases large amounts of methane which is considered an earth warming gas. Just like methane , greenhouse gases are released. Greenhouse gases add to the greenhouse house affect which causes global warming. The gases help trap heat making temperatures. The raise of the temperature has been affecting humans and animals.
“Their influence is known as the greenhouse gases, which are carbon dioxide, chlorofluorocarbons, methane, nitrous oxide, ozone, and water vapor”(“American Meteorological Society 2007”). These gases mixes with the sun ultraviolet rays, disburse into the earth atmosphere with harmful results. Carbon dioxide from the burning of fossil fuels is one way the human activities effects the environment. Carbon dioxide from the exhaust of cars in heavily polluted cities, farming machinery such as tractors, and smokestacks of refinery companies are just some of the ways carbon dioxide gases are release into the atmosphere by human contributors. The nitrous oxide gases affect the aquatic ecosystem food web chains, which leads from the smallest phytoplankton up to the largest mammal, which is man.
Energy can be converted to useful forms by various means. Energy and its conversion between forms can be expressed quantitatively. When converting energy, a significant fraction of that energy can be lost from the system (in the form of heat, sound, vibration, etc.) For example: in a power plant burning coal will produce heat energy, heat energy transfers to the water causing water to turn into steam, steam moves the turbine due to pressure, energy has now transferred from heat to mechanical energy, then mechanical energy is converted to electrical energy by the generators, here we have a good example of energy converted to another form. Define what we mean by fossil fuels and explain why there an attractive source of energy.
