First, before we talk about the importance of oil, we should know about what is oil.
Oil is a substance in a liquid state at a warmer temperature. It is nonpolar substance. Oil is both hydrophobic and lipophilic.
There are two types of oil. One is Mineral oil, another one is Organic oil.
All the oils contain high carbon and hydrogen. They all come from the organic material, for example, the dead plankton from ancient time. During the geochemical process those materials were converted to mineral oil, or petroleum. The compositions of the mineral oils are kerosene, parafiin waxes, gasoline, diesel and else.
They classified into mineral oils because they don’t have the organic origin on human time line. They were identified by the underground geologic locations.
The organic oils come from the plants, animals, and other organisms. Those oils, fats, wax, and cholesterol substances in scientific term are called lipids.
Oils can use in many different ways.
We use the food oil to cook, the fried foods even much hotter than the spoil water.
We use the oil as fuel, energy resource, for driving, heating, lighting, and so on.
We also use the oil for painting, since the color pigments, the slow drying process and mix of oil are help the artist to draw in realistic style.
Obviously, I am going to talk about the oil as fuel. Today, it does not just used for the energy resource, it also used for the economic and political issues.
