Energy
Four Source of Energy: Chemical, Solar, Mechanical, and Nuclear
Energy is used in every aspect of our lives, from power for transportation, to heat and light in dwelling and working areas, to the manufacture of good of all kinds. The development of science and civilization is closely linked to the availability and development of energy in useful forms. In this paper I am going to show four extremely vital forms of energy that we humans use everyday, and without which we could not enjoy the luxuries of life; like watching T.V., playing on the computer, and tracking the weather.
The first type of vitally important energy is Chemical. It utilizes the energy release from chemical reaction. The energy is both release and absorbed by the elements involve in a chemical reaction, but no lose occur in the molecular weight of the elements. Even thought this is true, the physical properties may change. Take for instance, the decomposition of water. In its molecules, each of which consist of one atom of oxygen 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 have two different properties from the water molecules they came from. Water, for example, does not burn nor does it support combustions, but 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, just like the one mentioned above, can be classified by the characteristics of the particular 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 part of them.
We can use the reaction from nuclear fusion or fission to obtain energy. We can use the steam from water to get energy. There are ways in which use the...
