~`Is Petroleum Liquid Gas  different  from  petroleum˙˙˙?
444489
Yes the two are different in their chemical compositions. Liquid petrolium gas, commonly known as LPG is a derivative of petroleum and is generally used as cooking gas.

oil as it comes out of the ground is not all the same. Some contains a lot of sulfur and some is thicker than other. Light sweet crude is oil that is not too thick--does not contain a lot of heavier hydrocarbon molecules. Sweet means that it does not contain a lot of sulfur.  Light sweet crude is considered the best oil to refine. There is not a lot of sulfur to get rid of and it is easy to crack.

Not sure I understand what you are asking.\nYou can choose to specify either temperature or pressue at the saturation point, but not both.\n\nIf the refrigerant is boiling, that's a 2-phase solution. The mixture will range from all liquid to all gas without a change in pressure or temperature. It will be saturated vapor by definition.\n\nFor common refrigerants it is probably simpler to look up the information - it should be published or at least available from the manufacturer.

Some countries still use "Petrol station". Gas is colloquial usage. \nGas is derived from the word Gasoline, which is another name for petroleum.

None. They are two different compounds.\n\nIt looks like you want to compare a specific property of the alcohols. Please specify!

omg this 1 toootally got me!!\n\nhttp://www.liquidgeneration.com/content/a55hat.aspx?cid=316\n\njust scroll down n click "begin" ....boo!!

This is a fair point, and I actually did this problem in a class at some point.  The bottom line is that any cost difference is going to be very small, but there can indeed be some difference.  And as the previous poster pointed out, the gas is stored in a well-insulated, underground environment, which makes any differences even more negligible.\n\nThe difference can be more pronouced if a tanker truck fills up in a 90 deg F area, drives all day and delivers to a 40 deg area.  Here, there is enough of a volume change to be noticeable.

ah DA petroleum MEANS oil . natral gas is methan and it come from decaing plant and animal matter. its usally found around coal and oil often found at same time coal an oil are from the same thing is why

Gasses are categorized as being able to expand to fill their given environment. So Play-Doh is not a gas.\n\nLiquids are categorized as being able to flow, and transport waves. However imagine a sea of Play-Doh. Could you imagine waves? If you try to apply enough force to cause such a wave in Play-Doh, you will permanently disfigure your model. If you take Play-Doh and smack it against the wall, it will fall off, not splash. Therefore Play-Doh is not a liquid.\n\nPlay-Doh therefore has to be a solid mixture. In fact if you want to get really technical it is a supersaturated aqueous solution of water - so saturated that it is a solid.

A solid, unlike a liquid or a gas, does not take the shape of its container.\nPour some water into a glass and the water takes on the shape of the glass, pour this water onto the floor and now the water has an entirely different shape.  The same goes for gasses.  However, put some solid object in a glass, on the floor, ..., and it still has the same shape.\n\nBoth solids and liquids have definite volumes, unlike gasses.  Solids and liquids are considered "incompressible".  No matter how much you squeeze them, they retain their volume.  Gasses however can be compressed/expanded depending on the force acting on them.

All alkanes exist as two or more isomers is not true\n\nbecause methane, ethane and propane are also alkane, but they have no isomers.

a.)\n\nIn a liquid or a gas, not all molecules have the same kinetic energy.  Temperature is just a measure of the average kinetic energy.  There is statistical range of kinetic energies.  Those molecules that have the higher kinetic energy may escape from the liquid into the gas phase.

Natural gas comes from the ground like oil, except that it's a gas and not a liquid. There are pockets of it all over the world (again, similar to oil).\n\nIt produces electricity similar to a car engine. Some engines are designed to run on natural gas instead of gasoline. Once the engine gets running, it is hooked up to a generator which produces electricity.

Question -   HOW MANY GAL.OF CRUDE OIL IN A BARREL? HOW MANY GAL OF GAS\nDOES THAT EQUAL?\n-----------------\nThere are 42 gallons / barrel of crude oil. The conversion to gasoline\ndepends upon several factors -- refining efficiency, product mix desired by\nthe refiner, quality of the crude to name a few. The following sites provide\nadditional info.\n\n http://www.petroleum.org/petrokids/petroperbbl.htm\nhttp://www.newton.dep.anl.gov/askasci/gen99/gen99675.htm\n\nVince Calder\n=====================================================\nA barrel contains 42 gallons.  After refining, it makes about 19.5 gallons\nof gasoline in addition to numerous other products such as heating oil..\n\nIf you can get to the web,\nhttp://www.petroleum.org/petrokids/petroperbbl.htm\nhas many interesting numbers related to your question.\n\nBest, Dick Plano, Professor of Physics emeritus, Rutgers University\n=====================================================\nBernie,\n\nMost of us know that the standard measure for petrol products, crude, light\nsweet etc... is the BBL (barrel).  This is exactly equal to 42 gallons.\nWhether it is milk or molten uranium or gas or crude oil...1 BBL (barrel) is\n42 gallon (US)\n\nI do not know the exact ratio of octane 87 gas to brent oil, light sweet\nblend, or crude oil.  This is because "OIL" is made up of many constituents.\nIt has many long changed hydrocarbons that determine its energy content.\nRefineries of the OPEC nations, or just in general already know this from\nyears of experience.  In order to not waste any of the crude oil, chemical\nengineers will perform hydro-cracking which will cleave the longer (CRUDEr)\noil chains into smaller more volatile compounds.  Why is this done?  This is\ndone so that while distilling the "OIL" engineers will not be able to\nseparate the oil with greater ease and efficiency.\n\nSomeone once told me that there was a rule of thumb for how many gallons of\n"gasoline" you can get from one gallon of crude.  I don't wish to repeat it\nsince I don't recall which blend it was for.  I hope that I've helped you\nsome even though I haven't fully answered your 2nd question.\n\nRegards,\nDarin\n=====================================================\nMy old CRC chemical handbook has it that a US petroleum barrel is exactly 42 gallons.\n\nCrude oil gets changed into petroleum gas, gasoline, oils, tar, and asphalt.\nThe total volume of the non-gaseous products will be not much different than the crude \nvolume.\n\nWhat percentage do they refine into gasoline? I don't know yet.\nAnything from 30-70% wouldn't surprise me.\nThey have both choices and pressures as to what product to make from crude.\n( See http://www.oiltycoon.com/htp/refining.html)\nA person at www.elitetrader.com/vb/showthread.php?threadid=33287 says it's about 2/3.\nThe other product made from the remaining 1/3 of a barrel gets sold too.\n\nSo that would be roughly 28 gallons of gasoline from each barrel of oil.

LP-Gas is odourless and non-toxic. A distinct smelling odourant such as ethyl mercaptan is added as a detection agent for all domestic, and for most commercial and industrial LP-Gas The purpose is to introduce sufficient odourant so that the presence of unburnt gas can be readily detected before it reaches a mixture that is flammable and comes in contact with a source of ignition.\n\n\n\nWhen you start using LPG, some of the pressure in the container is released. Some of the liquid LPG then boils to produce vapour. Heat is needed to convert the liquid to vapour (known as the latent heat of vaporization). As the liquid boils, it draws the heat energy from its surroundings. This explains why containers feel cold to touch and why, if there is a heavy off-take, water or ice may appear on the container. When you stop using LPG, the pressure will return to the equilibrium value for the surrounding temperature. The pressure of the LPG in the container varies with the surrounding temperature. It is also much higher than is needed by the appliances that use it; it needs to be controlled to ensure a steady supply at constant pressure. This is done by a regulator, which limits the pressure to suit the appliance that is being fuelled. It is a colourless and odourless gas to which foul-smelling mercaptan is added so that leak can be easily detected.

Well. Okay its like this. Most times a chemical in a can is gas, but while its in the can its liquid. This is because of pressure. It pressurizes it to a point of where it would be if it were really cold. When something that is a gas at room temperature is cold, say below freezing, it would be liquid. When its compressed to a liqid state it is going to be cold. I hope this makes sense. Instant message me if it doesnt and ill explain more.

all things have a solid liquid and gas state. it just depends on the temperature.
