“The fuels are made by separating and chemically changing petroleum compounds, a process referred to as refining (Farrauto). Diesel and gasoline are both made up of many different hydrogen-carbons, which are “compounds of consisting of hydrogen and carbon elements” (Farrauto). However diesel carbon atoms are in longer chains than gasoline. “Diesel chains have 14 carbon atoms whereas gasoline chains have 9” (Farrauto). The main differences between diesel and gasoline are as follows: “a) A diesel Engine takes air into the cylinder and compresses it.
In Ohaake in New Zealand about 320 gm of C02 is produced for each KW hour of electricity produced against 950 to 960 gm. if coal was used. Limitations Geothermal energy is a proven economical resource with energy technology. It has some environmental problems: 1. The steam brings hydrogen sulphide gas to the surface and pollutes the air unless controls are instituted.
Other major factors that make air pollution problem worst include: power and heat generation, the burning of solid wastes, industrial processes, and, especially, transportation. The six major types of air pollutants are carbon monoxide, hydrocarbons, nitrogen oxides, particulates, sulfur dioxide, and photochemical oxidants. Air pollution has been a major issue in Tehran, the capital of Iran. Three articles have been summarized, which evaluate the causes of air pollution in Tehran, the health concerns while explaining short-term and long-term remedies that the government of Iran has suggested. Air over Iran's capital is among the most polluted in the world, health experts say many Iranians suffer serious health problems as a result.
Acetylene gas is shipped in special cylinders designed to keep the gas dissolved. The cylinders are packed with porous materials (e.g. kapok fibre, diatomaceous earth, or (formerly) asbestos), then filled to around 50% capacity with acetone, as acetylene is acetone soluble. This method is necessary because above 207 kPa (30 lbf/in²) (absolute pressure) acetylene is unstable and may explode. There is about 1700 kPa (250 psi) pressure in the tank when full.
Future possibilities and environment benefits, there’s a study that it lessen the air pollution by using it. Abundant domestic production, increased resale value and more affordable maintenance. As evidenced in the Environment Protection Agency, natural gas as the cleanest fossil fuel was used in many ways to help reduce the emissions of pollutants into the environment. Burning natural gas than other fossil fuels emits fewer harmful pollutants and increase the reliance on potentially reduces emission of those many harmful pollutants. The use of natural gas does not significantly contribute in the formation of the smog as it emits lower nitrogen oxide and doesn’t have particulate matters.
The consequence of climate change is serious. It will cause sea level rises，more flooding and stronger storm. Secondly, the shortage of fossil fuels is also a big problem, which is means fossil fuels are finite and non-renewable. If people cannot use them reasonably and economically, fossil fuels will be used up very soon. Klass model is a good illustration of this problem and it assumes a continuous compound rate and computes fossil fuel reserve depletion times for oil, coal and gas of approximately 35, 107 and 37 years, respectively (Shahriar & Erkan, 1).
Gas Stoves vs. Electric Stoves What is the difference between a gas or electric stove? Gas stoves and electric stoves compare, but differ from one another in many aspects. How do they differ within cost, efficiency, and danger? What are the price ranges? Is there really a difference in efficiency?
In spite of this, if one compare this price to the amount of CO2 depleted by petrol and diesel vehicles , it gives the idea that if all classic cars would be supplanted with electric ones, CO2 emissions would be diminished by about 500 times. Despite the fact that Electric cars are moderately new at the mass production scale and are not yet answering many demands of improved expense, range and charging pace. Each of which will be aided by enhancing
The Affects on Human’s and the Environment Katrina Doughty Everest University September 2011 Air pollution consists of gases and fine particles. Each type of air pollution has different effects upon the environment and human health. Air pollution affects are many, and they may be really harmful. Three factors determine the levels of air pollution are the amount of pollutants entering the air, the amount of space into which the pollutants are dispersed, and the mechanisms that remove pollutants from the air. Sulfur dioxide is a noticeable component in the atmosphere.
In an era where depletion of fossil fuels a major problem and pollution an even bigger issue,it is only the alternate sources of energy which can meet the energy requirements of the future. So today i gaurav grover of class 10-b is here to share my views on the topic alternative sources of energy. Fossil fuels are an important part of life. When you turn on the lights, watch TV, or take a shower, the electricity that you are using is being generated by fossil fuels. The three types of fossil fuels are coal, crude oil, and natural gas.
