Can you answer a serious question for me?

Question

On the web, I was looking for the freezing point of gasoline. To no avail. The following ignorami plagarized answers and provided completely useless info: Tom, yonthejuggler, badbuick87, texasfirefighter, and Y!A's own embi40. (They must be retarded, and have brain malfunctioning issues.) No additivies, no avgas, just plain old unleaded gas, what is the freezing point? It is not complex. I am just looking for a number, and a verifiable and veritable source.

Answer 1

Where have you been big guy? I looked it up on the web also, and there does not seem to be a definitive answer for the question. Jet fuel is supposed to freeze at -47C, but as for gasoline it just depends on the composition. With water in the gas it can freeze at 32F, of course. Other than that, it depends on the mixture. How much heavy hydrocarbons present and how much of the lighter and harder to freeze aromatics. Some of the aromatics in gasoline will not freeze until about 200F-300F in a laboratory setting. I looked up unleaded gas, and I didn't find a hard and fast number. I even had my crack team of gerbils looking it up for me.

Answer 2

Well, gasoline doesn’t really have just one freezing temperature, and in fact, gasoline isn’t made out of just one kind of molecule, but many different hydrocarbons. If you get it cold enough, it will get pretty hard. Freezing is a phase change, in which the symmetry of a system reduces -- a liquid with a random distribution of molecules turns into an orderly crystal in a true freezing phase change. Gasoline on the other hand, just has molecules that slow down as they get colder, and remain in a disordered state at lower temperatures (you might get some crystals of some hydrocarbons if you cool it slowly enough).

Different components have different freezing temperatures. The alcohols might freeze first, and some of the aromatic hydrocarbons freeze at very low temperatures, below that of dry ice. The fact that they are all mixed together also depresses the temperatures of onset of solidification.

An example of a common household mixture which doesn’t have much of a freezing temperature is liquid dish soap. It just gets goopier and eventually hardens up. I know this from experience, trying to wash dishes in an unheated cabin on a cold, winter morning. Glass is another example of something which doesn’t truly freeze or melt, although it becomes ductile and even liquid at high temperatures and rigid at low temperatures.

Answer 3

Wow. I searched the net and you would think you would find that somewhere but nooooooooooo. i found where you could PAY for the answer from ASTM. left me wondering if regular ol' gasoline DOES have a freezing point. I mean, they must use it in the arctic/antarctic, right?

maybe call a few mechanic shops, they might know or have an ASTM manual or some refernce book that gives the answer.
Sorry i can't be more helpful. Good Luck.

Answer 4

Hydrate is a frozen mixture of water and hydrocarbons. This bonding of water around the hydrocarbon molecule forms a compound which can freeze above 3°F (0°C). Hydrates can be found in pipelines that are saturated with water vapor. It is also common to have hydrate formation in natural gas of high BTU content. Hydrate formation is dependent upon operating conditions and gas composition

Answer 5

you don't state where you asked, but i'm guessing chemistry(?) did you look in Y!A for similar answers when you posted your "?" did you ask jeeves? when you're searching do you use the word gasoline? i wish i could be more help, but i've found by playing with variables when in a serious quest, some combination of wording will eventually bring me to my goal. good luck, and sorry i could not be of more help.

Answer 6

WELL, a lady once in alaska told me that at 100 degrees below zero everything freezes. THEY have heaters 4 their cars.

Answer 7

Fuel suppliers will have that info on their msds sheets. you should be able to down load .
