What is it called when harmful substances are released into the air water or soil?
What is it called when harmful substances are released into the air water or soil?
Pollutants are harmful substances in the air, water, or soil. Air that contains harmful particles and gases is said to be polluted.
What do cars emit that is bad for the environment?
Cars and trucks emit carbon dioxide and other greenhouse gases, which contribute one-fifth of the United States’ total global warming pollution. Greenhouse gases trap heat in the atmosphere, which causes worldwide temperatures to rise.
Which fuel does not cause pollution?
Hydrogen fuel cell vehicles Hydrogen-fueled vehicles emit virtually no hydrocarbons, particulates, carbon dioxide, or carbon monoxide. They are viewed as an especially attractive option for reducing green house gas emissions.
Which fuel causes least pollution?
explanation :- Natural gas is the cleanest burning fossil fuel.
Which fuel has the highest specific energy?
hydrogen
Which fuel causes least pollution a diesel?
Natural gas is the simplest form of hydrocarbon and perhaps the cleanest burning fossil fuel. The chemical formula is CH4.
Which fuel is best suitable for blast furnace process Sanfoundry?
Which fuel is best suitable for blast furnace process? Explanation: Coke is best suitable for blast furnace process as it also acts as a reducing agent in smelting iron ore.
Which fuel is partially carbonized?
Which fuel is partially carbonized and is considered as a primary stage in coal formation? Explanation: Peat is partially carbonized and decomposed material formed mainly due the transformation of buried vegetation.
What happens when LPG is inhaled in large concentrations?
LPG vapor is heavier than air. Inhaling LPG vapor at high concentration even for a short time can cause fainting and/or death. Inhaling of LPG vapor can cause irritation in nose and throat, headache and nausea, vomiting, dizziness and loss of consciousness.
Which product is obtained from the converter in the Bergius process?
Explanation: Bergius process is used to produce synthetic gasoline form low ash pulverised coal. This coal is finely divided into powder and is converted into a paste. 2.
Which fuel oil is used for obtaining gasoline?
crude oil
What is the raw material used for bergius process?
The process involves the hydroliquefication of brown coal, also known as lignite, into crude oil. The brown coal is ground into a fine powder and heated at 425–480 °C under 200–700 atm. pressure of hydrogen gas in the presence of a catalyst. Iron, molybdenum, and tin catalysts have all been used.
What percentage of gas is prepared from bergius process?
Overall, about 97% of input carbon fed directly to the process can be converted into synthetic fuel. However, any carbon used in generating hydrogen will be lost as carbon dioxide, so reducing the overall carbon efficiency of the process.
