If you put gasoline on a pan on the oven would it evaporates or combusts?

Question

Then what is the difference between evaporation of fuels and combustion?

Answer 1

Gasoline is a flammable liquid, not a combustible. In a flammable liquid, the vapors burn, not the liquid. At a certain temperature a flammable liquid gives off enough vapors to form an ignitable mixture with air. This temperature is called the flash point.

The flash point for common gasoline is about 90-100 F. In the absence of oxygen, it would simply boil away.

In your common stove or oven, once it reached its flash point the resulting vapors from the boiling would ignite because you mentioned a common stove or oven which is not a vacuum. In other words oxygen is present and yes it would ignite in your scenario. Even if you used an electric oven, the flashpoint is the important thing to remember. There is no direct flame, but the temperature itself will cause ignition.

So to answer the question you asked, the gasoline would evaporate and the resulting vapor would burn (if exposed to an open flame). So in essence it would evaporate. Gasoline will not combust.

Do not try this at home!

The difference between evaporation and combustion is that with evaporatives, the medium must first reach the flash point and evaporate in order to burn. The liquid never burns, it is the fumes that are on fire.

In a combustable, the liquid reaches a certain temperature and then burns AS a liquid and does not require vapors to form.

Answer 2

There was a story... urban legend probably... about a guy who's car's gas lines had frozen in winter. Supposedly, the guy poured some gasoline into a pot and tried to heat it up on his stove to then pour it into his car and thus, melt the frozen lines. Needless to say the guy blew up his house in the process.

Whether this is true or not is really irrelevant. The actual matter is that gasoline will burn quite quickly if exposed to a heat source. In the case of a gas oven, I'm sure the flames would ignite the vapors instantly. If using an electric stove it would probably take a little bit longer... emphasis on little.

When gasoline evaporates, it just means that it is turning into vapor. Vapor, in and of itself, does not ignite by itself, hence no combustion. Combustion involves burning fuel (gasoline or other).

Answer 3

well,in oven u r not exposing it to direct flame....right..i think it may evaporate bcoz,combustion only takes place in presence of oxygen..(i m not sure whether there is oxygen present inside oven when it heats food stuff..!)

but,Gasoline is rather volatile (meaning it readily evaporates) and combustion is burning in presence of oxygen..

hope this helps u

Aluminum foil is made for the oven. you may save aluminum foil in there for hours. The aluminum foil pan you have are the disposable ones. you utilize those once or twice and throw them away. they are going to be only superb! i've got used them a lot of cases. they're handy b/c once you're bringing tarts to somebody- you may deliver them in the aluminum field and don't care approximately getting the field lower back.

Answer 5

Since the vapors combust and not the liquid, it would combust.

Answer 6

I dont know but I wouldnt want to be around when the big bang comes my friend

Answer 7

try it and let us know how u get on-if u can! LOL!

Answer 8

u probably will have an explosion
