What are fossil fuels?Ans: Fossil fuels are defined as fuels made from the decomposition of dead remains of plants and animals for millions of years. As a result, humans always require certain materials to convert one form of energy into another in order to complete numerous tasks. Hydrogen fuel is a green fuel as hydrogen is readily available in the environment in ({{\rm{H}}_2}{\rm{O}},) hydrocarbons, and other organic matter. It is the fumes of liquid fuels that are flammable instead of the fluid. There are three major types of fossil fuels, they are coal, petroleum and natural gas. The calorific value of fuel can be defined as the amount of heat produced by the complete combustion of one unit of any fuel. be easy to store. Coal and petroleum are formed from the dead remains of living organisms that is why they are called fossils fuels. These sources of energy can help to protect our natural resources to a great extent. Calorific value : The amount of heat energy produced on complete combustion of 1 kg of a fuel is called its calorific value. Thus, we can differentiate different fuels on the basis of their calorific value for their efficient usage.
