Answers
Answer:
1. A fuel is any material that can be made to react with other substances so that it releases energy as heat energy or to be used for work. Wood, coal, peat, dung, coke, charcoal , petroleum, diesel, gasoline, kerosene, LPG, coal tar, naphtha, ethanol, natural gas, hydrogen, propane, methane, coal gas, water gas, blast furnace gas, coke oven gas, CNG, etc. are some useful fuels found in the world.
2. Renewable resources are solar energy, wind energy, geothermal energy, biofuels, cultivated plants, biomass, air, water and soil. In contrast, non-renewable resources are those that are available to us in limited quantities, or those that are renewed so slowly that the rate at which they are consumed is too fast.
3. Fossil fuels are made from decomposing plants and animals. These fuels are found in the Earth's crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil, and natural gas are examples of fossil fuels.
4. The burning of fossil fuel gives out harmful compounds like sulfur dioxide and nitrogen oxides. These substances will rise terribly high into the atmosphere, wherever they combine and react with water, oxygen, and other chemicals to form a lot of acidic pollutants, called air pollution.

4. Air pollution, breath problems etc.
5. An aftermarket conversion is a vehicle or engine modified to operate using a different fuel or power source. Conventional vehicles and engines from original equipment manufacturers (OEMs) can be converted to run on fuels like propane, natural gas, or electricity.
