It's in fact the burning of what we call "fossil carbon" that creates the imbalance: fossil fuels, coal, oil, natural gas. These substances are all mined. We have to dig them up or drill a well to release them. And this is carbon that was in the atmosphere millions of years ago....
It’s the gases natural gas and the burning of coal give off add to the overheating of the earth.A.that; whatB.that; that C.which; which D.that; which
Possible scenarios of ignition and explosion development in coal mines are discussed. A principal possibility of complete quenching of detonation and combustion with the use of a sheet consisting of inert particles is experimentally demonstrated. As the detonation quenching process is rather complicated, ...
Greenhouse effect is not bad. In fact, it is necessary for us to live on the earth.Carbon dioxide is one of the main greenhouse gases. Now, because of the burning of coal, oil and natural gas, more carbon dioxide is released in the air. The air holds more and more heat day by ...
Now, because of the burning of coal, oil and natural gas, more carbon dioxide is released in the air. The air holds more and more heat day by day. Greenhouse effect has caused many problems, such as the raise of the temperature of the earth surface and the raise of sea level. People...
2. Identifying the Scenario: The question refers to the burning of coal dust in a coal mine. Coal dust is a fine particulate form of coal that can be easily ignited. 3. Recognizing the Type of Combustion: In the case of coal dust in a coal mine, it can ignite without any external ...
Well, in the process, large vats of raw copper ore are burned slowly, for two or three months actually, to lower the sulfur content. And this burning, well…let’s look at the results. First, the mines were fairly remote, so there was no way to bring coal or other fuel to keep th...
The burning of coal not only consumes the oxygen in the house but also gives out poisonous gases. 3) 显然,找到替代能源对我们经济的稳定发展是至关重要的。 Apparently, finding alternative energy sources is essential to the steady development of our economy. 4) 太阳能电池( sola...
