whats the difference detween oil and gasoline?

Answer 1

The "crude oil" pumped out of the ground is a black liquid called petroleum. This liquid contains aliphatic hydrocarbons, or hydrocarbons composed of nothing but hydrogen and carbon. The carbon atoms link together in chains of different lengths.

It turns out that hydrocarbon molecules of different lengths have different properties and behaviors. For example, a chain with just one carbon atom in it (CH4) is the lightest chain, known as methane. Methane is a gas so light that it floats like helium. As the chains get longer, they get heavier.

The first four chains -- CH4 (methane), C2H6 (ethane), C3H8 (propane) and C4H10 (butane) -- are all gases, and they boil at -161, -88, -46 and -1 degrees F, respectively (-107, -67, -43 and -18 degrees C). The chains up through C18H32 or so are all liquids at room temperature, and the chains above C19 are all solids at room temperature.

The different chain lengths have progressively higher boiling points, so they can be separated out by distillation. This is what happens in an oil refinery -- crude oil is heated and the different chains are pulled out by their vaporization temperatures. (See How Oil Refining Works for details.)

The chains in the C5, C6 and C7 range are all very light, easily vaporized, clear liquids called naphthas. They are used as solvents -- dry cleaning fluids can be made from these liquids, as well as paint solvents and other quick-drying products.

The chains from C7H16 through C11H24 are blended together and used for gasoline. All of them vaporize at temperatures below the boiling point of water. That's why if you spill gasoline on the ground it evaporates very quickly.

Next is kerosene, in the C12 to C15 range, followed by diesel fuel and heavier fuel oils (like heating oil for houses).

Next come the lubricating oils. These oils no longer vaporize in any way at normal temperatures. For example, engine oil can run all day at 250 degrees F (121 degrees C) without vaporizing at all. Oils go from very light (like 3-in-1 oil) through various thicknesses of motor oil through very thick gear oils and then semi-solid greases. Vasoline falls in there as well.

Chains above the C20 range form solids, starting with paraffin wax, then tar and finally asphaltic bitumen, which used to make asphalt roads.

All of these different substances come from crude oil. The only difference is the length of the carbon chains!

Answer 2

Gasoline is what your car need to move. It's an explosive substance which the engine uses to create movement (see 4 strokes engine). Gasoline is consumed as it's used.

Oil is a substance your car's engine need to reduce friction and so to increase your engine's life. Oil is not combusted (is that the word ?) but burned inside, a term used to mean it will turn black with the time because the temperature it has dealed with hass "burned" its substances so i must be changed every 1000 miles..

Answer 3

Gasoline is a derivative of oil having a completely different refining process,Both products are obtained from refining crude oil.

Answer 4

Crude oil contains hydrocarbon chain molecules of all different sizes. Everything from wax to the lightest disolved methanes and ethanes.

Gasoline is made up of a couple of those hydrocarbon molecules: heptane and octane. These 2 types of specific hydrocarcon molecules are distilled out of crude oil.

Oil, like motor oil is also another specific type of hydrocarbon (or a couple, three different specific molecules) that is distilled out of crude oil. Motor oil is heavier than gasoline because the motor oil hydrocarbon molecules are heavier than heptane and octane molecules.

Answer 5

gasoline comes from refined oil. Oil comes out of the ground - gasoline comes out of a pump.

If you go to the filling station, I sure hope you have read the above!!

Good luck and I hope this helps!

Answer 6

Gasoline is actually a by-product from refining oil.

Answer 7

Both gasoline and oil (I assume you mean motor oil) are made from crude oil. Obviously using different "recipes".

Answer 8

Oil when refined properly becomes gasoline.

Answer 9

oil is a lubricant and also cools the parts of your motor,gas is the food for your motor,it is very flammable and is what your motor burns.true gas is refined from oil but the two are not interchangeable

Answer 10

Gasoline is refined from Oil. Its the inverse of what McDonalds is to food.
