Various components of the substance with molecules of differing lengths (ie. short chain, long chain, etc.)

Everyone gave a definition here is the layman's term to explain it.
Imagine a barrel of oil goes down a pipe with different stages. At stage one, the oil is heated and from this you may get motor oil, then it is sent to the 2d stage and heated and from this you may get gasoline and then sent to a 3d stage in which the oil is heated and you get jet fuel from it. Each state of heating seperates the oil in which a certain byproduct is produced and further processed.
This is all done in fractions. So if you heated up bacon, the "fraction" process would get you grease. You seperated the grease from the bacon by heat. Making gasoline is a lot more complex than this but then you understand the process.
What is a fraction. It is a part of a number. Gasoline and motor oil, are parts of crude oil. Like grease is part of the bacon.

When crude oil is distilled (heated up and then cooled) - it evapourates and different components come off at different points in the distalation tower.
-So the distillation tower splits crude oil separate bits (ie fuel for cars, fuel for planes, heating oils, tars, and differnt gases ethane methane etc etc) each seperate component is called a fraction...because it is a fraction of the whole bit that it has been split up from
A fraction is a mixture of hydrocarbons that comes out of the still at a particular level.

A 'fraction' is a group of molecules within a given boiling point range (derived from crude oil).

In fractional distillation, oils and gases (hydrocarbons) of different boiling points are separated in the column.
The word "fraction" in this case refers to the "part".

It is a reference to fractional distillation. Where a silo is used to distill crude oil, at various heights (each height corresponds to a temperature within the silo) different components of the crude oil are distilled out.

Is it not a reference to the refining process, where as the distillation heat increases, different "fractions" are boiled off, each one consisting of progressively lighter hydrocarbons?
Yes that's it. They are called fractionation columns. This information will enable you to do a google search, I reckon.

a simple and clear answer to u is
different liquid have different boiling points
so when a mixture of liquid is made to boil for example oil
as temperature increases and the boiling point of each separate liquid id reached then each components of the liquid reaches its vapour form
thus the liquid are separated in different vapours such different fractions..
this is the simplest answer i could write for you from my good chemistry knowledge that i have
