What is gas found in?
Natural gas, some of which is seen burning here, is often found near deposits of oil and coal. Oil, coal, and natural gas are fossil fuels. Natural gas is a fossil fuel. Like other fossil fuels such as coal and oil, natural gas forms from the plants, animals, and microorganisms that lived millions of years ago.
What are the 4 main natural gases?
They are known as the four natural gases and include the first four alkanes — methane, ethane, butane, and propane. An alkane is a hydrocarbon where single bonds link together each atom. Hydrocarbons are chemical compounds made up exclusively of carbon and hydrogen atoms.
Which element is a gas?
Elemental hydrogen (H, element 1), nitrogen (N, element 7), oxygen (O, element 8), fluorine (F, element 9), and chlorine (Cl, element 17) are all gases at room temperature, and are found as diatomic molecules (H2, N2, O2, F2, Cl2).
Is gas a fluid?
Liquids and gases are called fluids because they can be made to flow, or move. In any fluid, the molecules themselves are in constant, random motion, colliding with each other and with the walls of any container.
How is gas made?
Gasoline is made when crude oil is broken into various petroleum products through a process of fractional distillation. The finished product is then distributed to gas stations through pipelines. Gasoline is essential to running most internal combustion engine cars.
Which is natural gas?
What is natural gas? Natural gas is a fossil energy source that formed deep beneath the earth's surface. Natural gas contains many different compounds. The largest component of natural gas is methane, a compound with one carbon atom and four hydrogen atoms (CH4).
Where does our gas come from?
Natural gas comes from deep within the earth. The natural gas you use in your home may have come from thousands of miles away! The natural gas that we use to heat our homes and our water comes from deep under the earth. The gas is found in layers of rock with tiny holes - the rock holds the gas like a sponge.
What do humans use gas for?
Most U.S. natural gas use is for heating and generating electricity, but some consuming sectors have other uses for natural gas. The electric power sector uses natural gas to generate electricity and produce useful thermal output.
Is natural gas toxic?
Natural gas is colorless, non-toxic, invisible and odorless, although an odorant is added to all natural gas that is transported in Connecticut. Known as mercaptan, this odorant is an important safety measure because it provides a distinct smell (much like the smell of rotten eggs) in the event of a gas leak.

What is gasoline made of?
The bulk of a typical gasoline consists of a homogeneous mixture of small, relatively lightweight hydrocarbons with between 4 and 12 carbon atoms per molecule (commonly referred to as C4–C12). It is a mixture of paraffins ( alkanes ), olefins ( alkenes ), and cycloalkanes (naphthenes). The usage of the terms paraffin and olefin in place of the standard chemical nomenclature alkane and alkene, respectively, is particular to the oil industry. The actual ratio of molecules in any gasoline depends upon: 1 the oil refinery that makes the gasoline, as not all refineries have the same set of processing units; 2 the crude oil feed used by the refinery; 3 the grade of gasoline (in particular, the octane rating).
How many gallons of gasoline are in a container?
A typical gasoline container holds 1.03 U.S. gallons (3.9 L). Gasoline ( / ˈɡæsəliːn /) or petrol ( / ˈpɛtrəl /) (see the etymology for naming differences and the use of the term gas) is a transparent, petroleum -derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines.
Why does gasoline have sticky residue?
Gummy, sticky resin deposits result from oxidative degradation of gasoline during long-term storage. These harmful deposits arise from the oxidation of alkenes and other minor components in gasoline (see drying oils ). Improvements in refinery techniques have generally reduced the susceptibility of gasolines to these problems. Previously, catalytically or thermally cracked gasolines were most susceptible to oxidation. The formation of gums is accelerated by copper salts, which can be neutralized by additives called metal deactivators .
What fuel did the Allies use?
Prior to the American entry into World War I, the European Allies used fuels derived from crude oils from Borneo, Java, and Sumatra, which gave satisfactory performance in their military aircraft. When the United States entered the war in April 1917, the U.S. became the principal supplier of aviation gasoline to the Allies and a decrease in engine performance was noted. Soon it was realized that motor vehicle fuels were unsatisfactory for aviation, and after the loss of several combat aircraft, attention turned to the quality of the gasolines being used. Later flight tests conducted in 1937, showed that an octane reduction of 13 points (from 100 down to 87 octane) decreased engine performance by 20 percent and increased take-off distance by 45 percent. If abnormal combustion were to occur, the engine could lose enough power to make getting airborne impossible and a take-off roll became a threat to the pilot and aircraft.
How did gasoline evolve?
The evolution of gasoline followed the evolution of oil as the dominant source of energy in the industrializing world. Before World War One, Britain was the world's greatest industrial power and depended on its navy to protect the shipping of raw materials from its colonies. Germany was also industrializing and, like Britain, lacked many natural resources which had to be shipped to the home country. By the 1890s, Germany began to pursue a policy of global prominence and began building a navy to compete with Britain's. Coal was the fuel that powered their navies. Though both Britain and Germany had natural coal reserves, new developments in oil as a fuel for ships changed the situation. Coal-powered ships were a tactical weakness because the process of loading coal was extremely slow and dirty and left the ship completely vulnerable to attack, and unreliable supplies of coal at international ports made long-distance voyages impractical. The advantages of petroleum oil soon found the navies of the world converting to oil, but Britain and Germany had very few domestic oil reserves. Britain eventually solved its naval oil dependence by securing oil from Royal Dutch Shell and the Anglo-Persian Oil Company and this determined from where and of what quality its gasoline would come.
What was the effect of the increase in gasoline consumption in 1910?
These would often be used in aircraft engines. By 1910, increased automobile production and the resultant increase in gasoline consumption produced a greater demand for gasoline. Also, the growing electrification of lighting produced a drop in kerosene demand, creating a supply problem.
Why is LPG less energy?
The lower energy content of LPG by liquid volume in comparison to gasoline is due mainly to its lower density. This lower density is a property of the lower molecular weight of propane (LPG's chief component) compared to gasoline's blend of various hydrocarbon compounds with heavier molecular weights than propane.
Why do refineries put ethanol in premium gas?
This is because they have to use the ethanol to raise the octane level of their gasoline blend in order to satisfy the higher octane requirements of premium.
Does premium gas have ethanol?
There is a difference between states on whether premium gas specifically has ethanol in it or not . Or, more correctly, whether it's required to have it in it. Two states in the Union, Missouri and Montana, have specific exemption to allow ethanol-free premium gasoline. So if you live in one of those two states, you can be thankful.
What Is The Percentage Of Ethanol In 93 Octane Gas?
Before looking at the percentage of ethanol in 93octane, it is prudent to know its significance. As mentioned, ethanol helps in the oxygenation of the fuel to see that it burns completely. In the long run, it reduces emissions and conserves the environment.
Final Words

When was lead added to gasoline?
Politicizing the science: lead’s long history of exhaust contamination. Tetraethyl lead was originally added to gasoline in the 1920s as an anti-knock agent to keep engines running smoothly, and manufacturers then claimed the additive was safe. Health experts at the time knew better.
When did the 05 gallons of gasoline go into effect?
1, 1996, but the EPA confirmed that the definition for unleaded gasoline allowing the .05 gram per gallon has been in effect since 1974. The definition is outlined in the “Protection of the Environment” section of the Code of Federal Regulations.
Why did lead increase in gasoline?
In the 1950s, the use of lead additives in gasoline began to increase due to growing automobile sales, the expansion of the U.S. highway system, and the decline of public rail transit systems, according to Mielke.

Gasoline or petrol (British English and Australian English; /ˈpɛtrəl/) (see Etymology for naming differences and geographic usage) is a transparent, petroleum-derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines (also known as petrol engines). It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhan…
Etymology
"Gasoline" is an American word that denotes fuel for automobiles. The term is thought to have been influenced by the trademark "Cazeline" or "Gazeline", named after the surname of British publisher, coffee merchant, and social campaigner John Cassell. On 27 November 1862, Cassell placed an advertisement in The Times of London:
The Patent Cazeline Oil, safe, economical, and brilliant [...] possesses all the requisites which ha…
History
The first internal combustion engines suitable for use in transportation applications, so-called Otto engines, were developed in Germany during the last quarter of the 19th century. The fuel for these early engines was a relatively volatile hydrocarbon obtained from coal gas. With a boiling point near 85 °C (185 °F) (n-octane boils about 40 °C (104 °F)higher), it was well-suited for early carburetors (evaporators). The development of a "spray nozzle" carburetor enabled the use of less volatile fu…
Chemical analysis and production
Commercial gasoline is a mixture of a large number of different hydrocarbons. Gasoline is produced to meet a host of engine performance specifications and many different compositions are possible. Hence, the exact chemical composition of gasoline is undefined. The performance specification also varies with season, requiring more volatile blends (due to added butane) during winter, in order to be able to start a cold engine. At the refinery, the composition varies accordin…
Physical properties
The specific gravity of gasoline ranges from 0.71 to 0.77, with higher densities having a greater volume fraction of aromatics. Finished marketable gasoline is traded (in Europe) with a standard reference of 0.755 kilograms per liter (6.30 lb/US gal), and its price is escalated or de-escalated according to its actual density. Because of its low density, gasoline floats on water, and therefore wat…
Octane rating
Spark-ignition engines are designed to burn gasoline in a controlled process called deflagration. However, the unburned mixture may autoignite by pressure and heat alone, rather than igniting from the spark plug at exactly the right time, causing a rapid pressure rise that can damage the engine. This is often referred to as engine knocking or end-gas knock. Knocking can be reduced by increasing the gasoline's resistance to autoignition, which is expressed by its octane rating.
Additives
Gasoline, when used in high-compression internal combustion engines, tends to auto-ignite or "detonate" causing damaging engine knocking (also called "pinging" or "pinking"). To address this problem, tetraethyl lead (TEL) was widely adopted as an additive for gasoline in the 1920s. With a growing awareness of the seriousness of the extent of environmental and health damage caused by lea…
