Chemical energy is another of the manifestations of energy and specifically it is the internal energy that a certain body possesses and although it can always be found in matter, it will only be shown to us when there is a significant alteration of it. Putting it in simpler terms, chemical energy is that which is produced by chemical reactions.
Among the most everyday examples that we can give of chemical energy are: the energy that comes from coal when it burns, batteries, batteries, among others.
Chemical energy is one of the many forms that energy has. It is also worth noting that this type of energy is always present in matter, as it will manifest itself when there is a specific modification of it.
So, chemical energy is the that produce simply and simply the chemical reactions that give off heat or, failing that, due to the violence they manifest, they develop some type of movement or work.
Once burned fuels produce violent chemical reactions that generate work or movement. At present, chemical energy is that which allows the mobilization of automobiles, ships, airplanes and any other machine. For example, the combustion of coal, oil and firewood in steam engines, as well as those derived from oil in the very small space of a cylinder of an internal combustion engine, have chemical reactions.
On the other hand, coal and gasified gasoline combine with the oxygen in the air, react with it and manage to transform slowly and smoothly, such is the case of coal, or instantaneously and abruptly in the case of gasoline within the engine cylinders; the flaming gaseous mixtures expand and in just an instant they will be communicating their energy to the engine pistons.
For an engine to start working, it will require fuel that, once reacted, will release energy. In internal combustion engines, the energy of the fuel used is transformed into power and movement and that force is precisely what is used to operate a vehicle, the propeller of a helicopter, a generator, among others.
Food, chemical energy in our body
Food can also be taken as a clear example of chemical energy, since once they are processed by the body they will offer us heat (calories) or they will become sources of natural energy (proteins and vitamins).
In addition, these foods will be essential when it comes to forming and renewing the tissues of our body, to maintain temperature or to allow us to carry out a muscular exercise.
Because food has nutrients such as carbohydrates, vitamins, proteins and lipids, formally called biogenetic , for having an organic origin. Meanwhile, inorganic nutrients are water and some minerals such as sodium, sulfur, phosphorus, zinc, manganese, and chlorine, among others.
Now, the energy that organisms will obtain can be produced in two ways: autotrophic or heterotrophic. While the first is the typical nutrition of plants and algae, which from carbon dioxide and the energy of the sun will generate glucose and oxygen, the second, for its part, is that of animal organisms and of the human being who ingest the food that has been previously elaborated, normally by autotrophic organisms, and meanwhile, it will be their cells that will oxidize it through perspiration and thus produce water vapor, carbon dioxide and waste substances.
And one of the most recent and spectacular applications of chemical energy has undoubtedly been in regard to, on the one hand, the journey of back and forth to outer space and the moon and on the other hand the installation of various types of artificial satellites in orbits. For a long time it was a utopia but today it is already possible thanks to this type of energy. With this we discover the importance that this type of energy has in the development of various activities and human actions that tend to search for novelties.
