The general definition of oil includes classes of chemical compounds that may be otherwise unrelated in structure, properties, and uses.
Oil has been used throughout history as a religious medium.
Oils are used as fuels for heating, lighting (such as a kerosene lamp), powering combustion engines, and other purposes.
Oils used for this purpose nowadays are usually derived from petroleum (including fuel oil, diesel oil, and gasoline), though biological oils such as biodiesel are also used.
Most oils burn in air generating heat which can be used directly or converted into other forms of energy in the usual ways.
Mineral oils are more suitable than biological oils, which degrade rapidly in most environmental conditions.
Several edible vegetable and animal oils, and also fats, are used for various purposes in cooking and food preparation.
Specially prepared oils are used in some religious ceremonies as purifying agents.
The slow drying process and miscibility of oil facilitates a realistic style.
Health advantages are claimed for a number of specific oils such as omega 3 oils (fish oil, flaxseed oil, etc) and evening primrose oil.
Color pigments can be easily suspended in oil, making it suitable as supporting medium for paints.
Oil paints have been used since the fifteenth century.
Oil allows massage strokes to glide along the skin.
A relatively high-viscosity oil such as almond oil may be used for a luxuriant, slow style; a lighter oil such as grape seed oil may be selected for a rapid approach.
Given that they are non-polar, oils do not easily adhere to other substances.
Many oils have higher boiling points than water and are electrical insulators, making them useful for liquid cooling systems, especially where electricity is used.
Biological oils are renewable and do not produce net carbon dioxide, but require land to grow.
Crude oil can be processed into plastics and other substances.
Trans fats, often produced by hydrogenating vegetable oils, are known to be harmful to health.
The oil sector operates through the state-owned Petrуleos de Venezuela (PDVSA), whose subsidiaries include the distributor CITGO.
Oils are also used for flavoring and for modifying the texture of foods (e.g Stir Fry).
Petroleum products include transportation fuels, fuel oils for heating and electricity generation, asphalt and road oil, and feedstocks for making the chemicals, plastics, and synthetic materials that are in nearly everything we use.Sep 27, 2017
The engine oil filter is usually also changed at the same time. Automobile engines have many moving parts. As these parts move and rub against each other, the force of friction creates heat. Oil lubricates the engine and absorbs heat, allowing the internal parts to work together effectively without overheating.
The petroleum industry, also known as the oil industry or the oil patch, includes the global processes of exploration, extraction, refining, transporting (often by oil tankers and pipelines), and marketing of petroleum products. The largest volume products of the industry are fuel oil and gasoline (petrol).
Petroleum is basically a mix of naturally occurring organic compounds from within the earth that contain primarily hydrogen, carbon and oxygen. When petroleum comes straight out of the ground as a liquid it is called crude oil if dark and viscous, and condensate if clear and volatile.Oct 16, 2015
Home Heating Oil Advantages & Benefits. OIL HEAT ADVANTAGES: Oil heat is the safest, most efficient means to heat a home or business. Fuel oil is a very stable, combustible, non-explosive product, which addresses some of the safety concerns that surround other fuels.
It's easy to understand why oil is so important in our lives. ... Gasoline is made from crude oil. Lubricating oil is also used to keep our automobile engines from getting too hot and to ensure that all moving parts of the machinery are kept in good working order.Jan 31, 1983
Oil: lifeblood of the industrialised nations Oil has become the world's most important source of energy since the mid-1950s. Its products underpin modern society, mainly supplying energy to power industry, heat homes and provide fuel for vehicles and aeroplanes to carry goods and people all over the world.
