Petroleum fractions are components of crude oil that have been separated through a process called fractional distillation. During this process, crude oil is heated to high temperatures, causing it to vaporize. The different components of the crude oil vaporize at different temperatures, allowing them to be separated into fractions such as gasoline, diesel, and kerosene based on their boiling points. These fractions are then further refined to produce various petroleum products used in industries such as transportation, manufacturing, and energy production.
Every fraction is an equivalent fraction: each fraction in decimal form has an equivalent rational fraction as well as an equivalent percentage fraction.
A fraction that has a different sign to the first fraction.
Divide the fraction by 100, and you will get the percentage of a fraction.
Or both. That's a complex fraction.
The number below the fraction bar in a fraction is the denominator. The number above the fraction bar is the numerator.
Petroleum is refined from crude oil and is but one fraction only
It depends on the petroleum. Petroleum is a mixture that varies from one area to another.
The petroleum fraction that has the lowest boiling point is natural gas, which consists mainly of methane with other hydrocarbons. It boils at temperatures below -162 degrees Celsius.
The first fraction to separate out of petroleum during fractional distillation is usually the lightest fraction, which includes gases like methane, ethane, and propane. These fractions have lower boiling points and are typically collected at the top of the fractionating column.

Energy, in the form of heat, must.
Exemples: white spirit, kerosene, diesel fuel, etc.
Feedstock is the stuff you start with... probably crude oil for petroleum chemistry, though you might begin with a particular fraction of the oil instead of crude.
Road tar is made from coal. Asphalt is a heavy fraction of petroleum.
Gasoline, kerosene, and crude petroleum are related in that they are all derived from the refining of crude oil. Crude petroleum is the raw material that undergoes refining processes to produce gasoline and kerosene, among other products. Gasoline is a lighter fraction of crude oil used as fuel for vehicles, while kerosene is a slightly heavier fraction often used as a fuel for heating and lighting.
use fractional distillation. the process works becuz the fractions have different boiling poing ranges
