CRUDE OIL PROPERTIES!!!!!?

can anybody help me with my chemistry assiagnment?


ive been looking all over the internet but can ot find the answers any were.


what is the boiling and freezing points of crude oil?





can anyone please help me!!!!!!!!!!!!CRUDE OIL PROPERTIES!!!!!?
You can't find the answer because there is no set boiling point or freezing point for crude oil.





Crude oil is unbelievably complex and dirty. It contains everything from gases to solid compounds that don't melt even at high temperatures (they decompose instead.)





Furthermore, every oil-field produces oil with a different composition so each oil will have some different properties from other oils.





To generalize, if you had a sample of crude oil and heated it from 0*C to several hundred degrees C, it would start out being extremely thick, nearly solid, and it would slowly soften and liquefy and vaporize as it was heated. There would be no solid-liquid-gas transition temperatures like you find for pure compounds, like water, for example.CRUDE OIL PROPERTIES!!!!!?
The boiling and freezing points of crude oil are not a fixed property:





Crude oils vary widely in appearance and viscosity from field to field. They range in colour, odour, and in the properties they contain.





While all crude oils are essentially hydrocarbons, the differences in properties, especially the variations in molecular structure, mean that a crude is more or less easy to produce, pipeline, and refine.





Crudes are roughly classified into three groups, according to the nature of the hydrocarbons they contain.





Paraffin-Base Crude Oils


These contain higher molecular weight paraffins which are solid at room temperature, but little or no asphaltic (bituminous) matter. They can produce high-grade lubricating oils.





Asphaltic-Base Crude Oils


Contain large proportions of asphaltic matter, and little or no paraffin. Some are predominantly naphthenes so yield a lubricating oil that is more sensitive to temperature changes than the paraffin-base crudes.





Mixed-Base Crude Oils


The ';gray area'; between the two types above. Both paraffins and naphthenes are present, as well as aromatic hydrocarbons. Most crudes fit this category.





You should get some idea of what鈥檚 involved from:

Crude oil is a complex mixture of hydrocarbons. The petroleum from different sources will have different properties since the composition will vary.





The various components within the mixture will boil at different temperatures and so giving a single boiling point is not a feasible option.





If you look up 'Petroleum' in Wikipedia you will get some idea about the complexity.
It is an organic mixture.


It doesn't have a definite boiling or a freezing point .
they are made from hydrocarbons.
