Fossil fuels can be made in the laboratory. State whether the given statement is True or False.
(A) True
(B) False
Solution
A fossil fuel is a fuel that is generated by natural processes, such as anaerobic decomposition of buried dead creatures, and contains organic molecules that were formed during ancient photosynthesis and release energy when burned. These creatures, as well as the fossil fuels they produce, are generally millions of years old, if not more than 650 million years old.
Complete answer:
As a result of anaerobic decomposition, aquatic phytoplankton and zooplankton that perished and sedimented in huge quantities under anoxic circumstances millions of years ago began to create petroleum and natural gas. Over time, this organic stuff, which was combined with muck, was buried beneath heavier layers of inorganic silt. The high temperature and pressure led the organic matter to change chemically, first into kerogen, a waxy substance present in oil shales, and then, with further heat, into liquid and gaseous hydrocarbons in a process known as catagenesis. The energy produced in combustion is still photosynthetic in origin, notwithstanding these heat-driven changes. Plants on the ground, on the other hand, tended to produce coal and methane. Many of the coal deposits date back to Earth's Carboniferous epoch. Terrestrial plants may also produce type III kerogen, which is a natural gas source. Despite the fact that natural processes continuously create fossil fuels, they are categorised as non-renewable resources since they take millions of years to produce and known viable reserves are exhausted far quicker than new ones are created. Any particular fuel contains a wide spectrum of chemical components. A fuel's distinctive characteristics, such as density, viscosity, boiling point, melting temperature, and so on, are determined by the precise blend of hydrocarbons it contains.
No, we can't make petroleum in the lab since it's also known as fossil fuel. Over millions of years, the remnants of animals and plants buried under the seas changed into fossil fuels under great pressure and high temperature. Because such an environment cannot be replicated in a lab, we are unable to prepare petroleum in one.
Note:
Because fossil fuels can be burnt (oxidised to carbon dioxide and water) and provide substantial quantities of energy per unit mass, they are extremely important. Coal has been used as a source of energy since before the beginning of time. Coal was used to fuel the smelting of metal ore in furnaces. While ancient peoples burnt semi-solid hydrocarbons from seeps, they were primarily utilised for waterproofing and embalming. Petroleum was first commercially exploited in the 19th century, primarily to replace animal-based oils (particularly whale oil) in oil lamps.
