strengthFour Source of Energy Chemical, Solar, Mechanical, and NuclearEnergy is used in every aspect of our lives, from power for transportation, to heat and light in legal residence and working areas, to the manufacture of good of on the whole kinds. The development of science and cultivation is closely linked to the availability and development of aptitude in utilitarian forms. In this paper I am going to show four-spot extremely vital forms of energy that we humans use everyday, and without which we could not make happy the luxuries of life like watching T.V., playing on the computer, and tracking the weather.The low type of vitally important energy is Chemical. It utilizes the energy release from chemical substance reaction. The energy is both release and absorbed by the elements involve in a chemical reaction, further no lose occur in the molecular weight of the elements. Even thought this is true, the physical properties may change. understand for instance, the decom position of water. In its molecules, each of which consist of one atom of atomic number 8 and two of hydrogen, are broken down the hydrogen atoms combine in pairs, and the oxygen atoms form oxygen molecules. The two new molecules now defy two disparate properties from the water molecules they came from. Water, for example, does not burn nor does it support burns, tho the new hydrogen molecule is now flammable and the oxygen is combustion supportive, both of which can be used to obtain useful forms of energy.The reactions, clean like the one mentioned above, can be classified by the characteristics of the item reaction. As anyone could observe we, the people of this world have many different forms of reactions to obtain the energy we desire. This chemical energy is pretty the base of all other forms of energy, or at least a big intermit of them.We can use the reaction from nuclear fusion or nuclear fission to obtain energy. We can use the steam from water to get energy. in t hat location are ways in which use the elements and the properties of their reaction to obtain energy.A type of energy that work is another form of chemical energy, but deserves its own individual respect, is the above-mentioned nuclear energy. With the development of nuclear energy in the early 20th century came available another fabulously great source of energy. It uses the heat from the nuclear energy and converts it into electricity. The nuclear is stored in the nucleus of an atom and is released though fission, fusion, or radioactivity.
