2. Lava Flows is the lava that slide down the side of the volcano. The dangers of hot lava meeting the surface are streams that resulted from the boiling of the salt water and the instantaneously change to a crystal. The water temperature where lava meets water is 30 -69. Volcanic Gases 1.
In the coal gasification process the air and stream are added to the raw coals then heat it to hundred degrees Fahrenheit. The carbon in the coal then react with the oxygen and the water then produces other gases such as carbon dioxide, carbon monoxide, hydrogen and methane. The carbon dioxide from the process is waste and can go to the atmosphere. The other gases can be burned or sent to the next process. Then the second process is after we get the processed and filtered coal, gas or water or carbon dioxide can be added to balance the amount of carbon monoxide and hydrogen.
Some mining involves the inadvertent dispersal of heavy metals, such as lead, into the atmosphere. This can have serious health effects 4. What can be done to prevent mine drainage from damaging the ecosystem? Utilize at least one scholarly resource to support your suggestions. Answer = According to World Coal, there are mining
Lab 4 – Energy Sources and Alternative Energy Experiment 1: The Effects of Coal Mining Table 1: pH of Water Samples | Water Sample | Initial pH | Final pH (24-48 hours) | Pyrite | 4.5 | 5 | Activated Carbon | 4.5 | 6.5 | Water | 4.5 | 4.5 | POST LAB QUESTIONS 1. Develop hypotheses predicting the effect of pyrite and coal on the acidity of water? a. Pyrite hypothesis = Adding pyrite to water it will cause the pH levels to increase. b. Coal hypothesis = If I add activated carbon to the water it will lower the pH level of the water.
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.
One of the ways to get it is called fracking. Fracking is short for hydraulic fracturing. What is fracking and what does it do to the environment? Fracking is a process where millions of gallons of a mixture of liquid are inputted into the ground at high pressure to break the rock surrounding the natural gas. Then the natural gas is discharged from the ground into a well.
The basis of gasification is to supply less oxidant than would be required for stoichiometric combustion of a solid fuel. Stoichiometric combustion occurs when all the carbon in the fuel is converted to CO2 and there is no excess O2 left over. Doherty, W. et al (2009) noted that the energy value of the useful gas is typically 75% of the chemical heating value of the original solid fuel and the syngas temperature will be substantially higher than the original solid fuel due to the gasification process. 2.8.5 Landfill gas (LFG) collection and utilization Landfills produce landfill gas by the degradation of organic matter under anaerobic conditions. The evaluation of any landfill gas recovery project is highly effected by the composition of waste, specifically the organic fraction, moisture level, and the “degradation” factor of different waste components.
stratospheric ozone). On the very long time scale tectonic activities which can cause changes in albedo are the key driver of climate change. The tectonics have had an impact on the levels of CO2 exchange between ocean, atmosphere and solid regions. Besides, volcanism often associated with tectonic processes has a big effect on climate change. Apart from emitting CO2, volcano erupts magma containing a large amount of SO2, which can create atmospheric H2SO4 aerosols.
With too many greenhouse gasses in the air, the earth’s atmosphere traps too much heat and light and eventually the earth get too hot and the temperature rises. This process of collective heat from the sun is called the greenhouse effect. Sometimes the temperature can change in a way that helps us. The greenhouse effect makes the earth appropriate for people to live on it. Without it, the earth would be freezing, or the earth would be extremely hot.
