Answer:
11) Smog is a kind of air pollution, originally named for the mixture of smoke and fog in the air. Classic smog results from large amounts of coal burning in an area and is caused by a mixture of smoke and sulfur dioxide. In the 1950s a new type of smog, known as Photochemical Smog, was first described.

13) pollutant is defined as any form of energy or matter that cause degradation. It also create pollution in the natural balance osf eco-system. ... Pollution is an undesirable change in the physical, chemical or biological characteristics of our air, land and water, that may or will affect human life adversely.
14) Chlorofluorocarbons (CFCs) are anthropogenic compounds that have been released into the atmosphere since the 1930s in various applications such as in air-conditioning, refrigeration, blowing agents in foams, insulations and packing materials, propellants in aerosol cans, and as solvents.
15) While CNG is comprised of methane, LPG is comprised of propane and butane. CNG is typically used as a substitute for gasoline in automobiles, while LPG is often used in the industrial, refrigeration, agricultural and catering industries.

ANS 11- Smog is a kind of air pollution, originally named for the mixture of smoke and fog in the air. Classic smog results from large amounts of coal burning in an area and is caused by a mixture of smoke and sulfur dioxide. In the 1950s a new type of smog, known as Photochemical Smog, was first described.
ANS 12 - The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. ... The absorbed energy warms the atmosphere and the surface of the Earth.
ANS 13 - A pollutant is defined as any form of energy or matter that cause degradation. It also create pollution in the natural balance of eco-system. ... Pollution is an undesirable change in the physical, chemical or biological characteristics of our air, land and water, that may or will affect human life adversely. 2.
ANS 14 -Chlorofluorocarbons (CFCs) are anthropogenic compounds that have been released into the atmosphere since the 1930s in various applications such as in air-conditioning, refrigeration, blowing agents in foams, insulations and packing materials, propellants in aerosol cans, and as solvents.
ANS 15 - While CNG is comprised of methane, LPG is comprised of propane and butane. CNG is typically used as a substitute for gasoline in automobiles, while LPG is often used in the industrial, refrigeration, agricultural and catering industries.
