Question

How is the energy stored in fossil fuels released?

Answer 1

Hint: Fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing organic molecules originating from ancient photosynthesis that release energy during combustion.

Complete answer:
By burning fossil fuels, we not only consume energy that has been stored for a million years, but also carbon that has been stored for a million years. This massive release of carbon (in the form of carbon dioxide) overwhelms the natural cycles that balance the amount of carbon dioxide in the air.

Fossil fuels are mostly hydrocarbons and burn with air oxygen in the engine or boiler. The products are thermal, carbon dioxide, and water. Fossil fuels, such as coal, oil, and natural gas, are produced when organic matter decays and is compressed under a layer of sand, earth, rock, and ocean.

The burning of fossil fuels produces carbon dioxide, water, and energy; the process of burning fossil fuels is known as "combustion." Energy is either absorbed into the environment (endothermic reaction) or released into the environment (exothermic reaction) during chemical reactions, and chemical bonds are broken and formed. Bond making is an exothermic process, while bond breaking is an endothermic process.

 Fossil fuels consist mainly of hydrocarbons which are converted into carbon dioxide and water during a combustion reaction.Of the three fossil fuels we know, natural gas is the cleanest to burn Coal and oil are more chemically complicated and release a cocktail of potentially harmful substances into the atmosphere when burned. Flora is used to detect Sulfur dioxide in combustion gases, fluorescence – induced by ultraviolet light is used.

Thus, the energy stored in fossil fuels is released by the process of combustion.

Note: Since the beginning of the Industrial Revolution in Britain in the second half of the 18th century, fossil fuels have been increasingly consumed. Today, more than 80 percent of all energy consumed by the industrially developed countries of the world is supplied.
