WRITE A NOTE ON HISTORY OF FUELS

Fuel can be defined as a contained substance that is compelled to generate heat and energy when it is burning.

Introduction 

Fuel is that particular substance that supplies power or energy while burning itself. It can be more dignified with certain examples such as coal, LPG, diesel, wood, petrol, and more. This substance is potentially enough to produce a huge context of energy upon combustion. The further discussion has been preceded by highlighting the history of fuel. In this process,  it has been explained with its interrelation with energy by defining title specifications such as what are fossil fuels, types of fuels, what are fuels, and more. 

Definition of energy 

Energy has been defined as extraction from chemical or physical resources to provide heat or light specifically for work machines. Energy is mostly observed to be derived from the mass utilization of chemical resources. It is provided by the application of an overall force imposed by its capital capacity to generate power. Energy can be also specified as a capacity to push through or move an object. It is the one that is verified by the given mass that is inclined to produce energy from that physical resource. Hence, to be more precise, it is that particular capacity for extracting the power or heat. 

What are fossil fuels? 

In the question of what fossil fuels are, it can be specified that fossil fuels are the particular substance that consists of hydrocarbons and is generally formed underground. This particular material is produced from the remaining dead plants as well as animals far beneath underground extracted and burned in the later process to release energy from it.  Hence, it can be clarified that the fuels that are extracted from the remains of dead plants and animals  and produce more energy are called fossil fuels.  It is followed by its significance that it is readily available as well as its production system of energy is far easier as compared to other types of fuels. 

What are fuels? 

To propose and answer the question of what fuels are, it can be addressed that fuels are that particular material or substance producing heat and energy while burning itself. In this context, it has a specific type of material that is a nutritive material that can use atomic energy when it is being reacted with other substances. It has been defined that the material that is contained that has again been mentioned as uranium-235, is allowed to produce energy as a nuclear reactor. In terms of this, coal, petroleum, Orimulsion, and natural gas can be classified as to declare what are fuels in order to be more precise. 

Types of fuel

Fuels can be differentiated as kerosene, gasoline, diesel oil, biodiesel, solar oil, fuel oil, after, avgas, and such. In this context, gasoline has been identified as the most widely used and common fuel of all time. It has been used for multiple purposes from domestic usage to industrial. Also, aviation gasoline (Avgas) is meant to be produced from small fractions of petroleum. 

Fuel as the determinant of energy 

While reacting to chemical changes, fuels are supposed to be providing energy and heat as a result.  This type of energy can be produced from the fuel combustion of light, electricity, heat, or motion transforming that energy to change its mode of conduction. Compared to fossil fuels,  petroleum can produce less energy as its combustion is 1 gram,  whereas, one gram of natural gas can produce more energy. 

Significance of fuel 

The primary and classified purpose of fuels is to generate energy and heat. Its calorific value is most signified as to materialize both its physical and chemical aspects as of gasoline. Therefore, these properties of gasoline can be deferred or varied far from that of diesel fuels. Identification has been made almost two million years ago, through the combustion of sticks and wood with the process of Homo-erectus, which is known as the first use of fuels. 

Conclusion 

Overall description has been made by explaining the core context of fuels. This particular context has been evaluated all through its history in terms of its usage, purpose, variants as well as extraction system. From the entire discussion it has been identified that it is destined to serve as to produce energy. It has certain categories that produce more or less energy. However, while explaining what fossil fuels are, it has been identified that natural gas can produce more energy as compared to petrol.
