Give two examples each of solid liquid and gaseous pollutants
Answers
Answer:
The examples of each solid, liquid and gaseous fuel are given as:
1) Solid Fuel: Coal, Wood - They are used for cooking purposes. Coal is also used in industries sometimes.
2) Liquid Fuel: Kerosene, Petrol – They are used as fuels in automobiles. Kerosene is also used in lamps.
3) Gas fuel: CNG, LPG – LPG is used as a fuel for industries.
Explanation:
Energy has strong impact on the environment, especially when fossil fuels such as coal, oil, gas, and wood are burned. The products will affect earth, buildings, water, and air. They consequently result in fog, smog, and global warming, which deteriorate vegetation, forests, and even human health. Human beings may be affected in the form of having asthma and even cancer Thousands of people in the world die each year due to heart and lung diseases that result from air pollution . During the combustion of fossil fuels, which constitute nowadays85%oftheworldenergyresources,manyharmful elements and gases are emitted from the vehicles, furnaces, stoves, and electric power plants Usually, the main combustion products of vehicular engines, gas turbines, and steam power plant furnaces are carbon monoxides (CO), unburned hydrocarbon UHC and nitrogen oxides (NOx)sulfur oxides (Sox), and soot, in addition to volatile organic compounds (VOC) Usually, children are the most susceptible to harmful influences due to their tender tissues and their higher surface/volume ratio, and the higher relative inhalation rate for healthier growth and buildup.
2 The greenhouse effect Glass allows the solar radiation to enter freely but blocks the infrared radiation emitted by the interior surfaces. This causes a rise in the interior temperature as a result of the energy buildup in the car. This heating effect is known as the greenhouse effect, since it is utilized primarily in greenhouses. The greenhouse effect is also experienced on a larger scale on earth.The surface of the earth,which warms up during the day as a result of the absorption of solar energy,cools down at night by radiating part of its energy into deep space as infrared radiation. Carbon dioxide (CO2), water vapor, and trace amounts of some other gases such as methane and nitrogen oxides act like a blanket and keep the earth warm at night by blocking the heat radiated from the earth. Therefore, they are called greenhouse gases.
