(Nitrogen, hydrogen, oxygen, carbon dioxide, and other elements cause weld defects if introduced to the weld pool.) After a while it was discovered that argon has some advantages over helium. Because argon is heavier than helium, less flow rate is needed. The lower flow rate requirement makes argon better for flat welding. Helium is good for overhead, because it is lighter and thus flows upward.
Water also controls our climate weathers. Warm body of water is evaporated, causing high level of wind intensity. For example, the southeastern coast of the US is annually pummeled by hurricanes and tropic storms. Although we would rather live without them, it is a way of balancing the atmosphere. Water is used in photosynthesis by plants, which produce oxygen - this reaction is vital for the earth as the oxygen produced is used by humans to breath Water is used in coal powered electricity stations.
B) Greenhouse gases prevent heat from leaving the earth. C) If the level of greenhouse gases increases, the temperature will decrease. D) Some greenhouses gases are needed to keep the proper temperature balance. E) none of the above 3) Which of the following is TRUE? A) Stoichiometry allows prediction of the amounts of products that form in a chemical reaction based on the amounts of reactants.
Thorium compared to Uranium creates less toxic waste and also unlike Plutonium (the by-product of uranium) the toxic waste created by Thorium will only takes 500 years to be declared safe. In addition, Australia has large reserves of Thorium. Australia should go nuclear because it has the resources, skills and the technology which will be able to create carbon dioxide free electricity which will reduce the global warming
The nuclear reaction of the sun travels outward and by the time it reaches the surface it is transformed into light energy (sunlight). When this energy reaches the Earth, it is in the form of heat and light. The heat from the sun is collected by one type of solar panel that is used to heat water for the home or to keep your house warm in the winter months. The light energy from the sun can be transformed into electrical energy to be stored or used immediately. The panel that converts light energy into electrical energy is called a Photovoltaic panel.
Scherrie Smith Environment Science EVS 1001-120 October 26, 2012 Professor Amanda Slaughter How Humans Impact in Carbon, Nitrogen, and Phosphorus Cycle. Carbon Cycle- is the circulation of carbon between living organisms and their surroundings. Carbon dioxide from the atmosphere is synthesized by plants into plant tissue, which is ingested and metabolized by animals and converted to carbon dioxide again during respiration and decay. The human impact on the Carbon Cycle is that human intrusion into the cycle is significant. We are diverting or removing 40% of the photosynthetic effect of and plants.
Environmental Science Irma Boric Everest University Online Natural gas is a highly flammable gas that is known as a hydrocarbon mixture. Natural gas is contains mostly methane and is the safest form of energy that we can use daily. When animals and buried plants get exposed to heat natural gas is formed. Because natural gas is a cleaner fossil fuel the carbon dioxide emissions are lower. Natural gas also isn’t high in nitrogen oxide or sulfur dioxide.
Carbon dioxide is an significant contributor to the enhanced greenhouse effect. It can result in trapping more of the heat that Earth is radiating into space and cause detrimental climate changes and rising sea levels. The main concern regarding the combustion of organic compounds is the result of incomplete combustion. Incomplete combustion occurs when there is not enough oxygen to completely burn the fuel to carbon dioxide and water, causing pollution and fuel inefficiency. For example: Pentane reacts with little oxygen to form
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.
Coal, natural gas, and oil are burned for energy in many ways such as cars and power plants. Forest burning for deforestation also causes C02 emissions. C02 emissions are harmful to the planet and cause the planet to heat up. Global warming causes worse weather conditions in the world amongst other issues. With so many issues that can arise with a hotter Earth, I believe this to be a major issue that needs to be addressed.
