Because crude oil is a mixture of different chemicals - mainly hydrocarbons - that have different evaporation temperatures. Roughly speaking, when the crude is heated, its temperature rises until it reaches the lowest vaporisation temperature. The temperature then remains more or less steady as the heat input is used as the latent heat of vaporisation for the relevant compound. When [almost] all of that compound has evaporated, the temperature starts rising again until it reaches the next varorisation temperature, and so on.

What is the difference between birth rate and crude birth rate?
Crude birth rate is how many live children are born. Crude death rate is how many people die. Crude death minus crude birth is the net gain (or loss) and is called the birth rate. It represents whether or not deceased people are "replaced".
What is true about I statement?
They made be crude or sophisticated
What does Black Gold refer to?
crude oilAnswerit is oil also know as Texas tea
What is the difference between an intelligent guess and crude guess?
a crude guess is just a mere guess while the intelligent guess is likely to happen due to your experience
What is the Difference between crude death rate and actual death rate?
Death Rate is the actual rate of death where Crude Death Rate is a guess on the death rate.
Why is a thermometer needed when separating crude oil?
A thermometer is needed when separating crude oil to monitor and control temperatures during distillation. Different components of crude oil have different boiling points, so heating the crude oil to specific temperatures allows for the separation of various fractions more efficiently. This helps to ensure that each component is collected at the appropriate stage of the distillation process.
How does naphtha separate from the other fractions of crude oil?
Naphtha is separated from other fractions of crude oil through the process of fractional distillation in a refinery. This process heats the crude oil to high temperatures, causing the different hydrocarbons within the oil to vaporize at different temperatures. Naphtha has a lower boiling point compared to other fractions, allowing it to be collected as a separate product.
Why the different fraction of crude oil are collected at different temperature?
Oils collected at different temperatures produce different oils, and distillate fuels. Gasoline, diesel fuel, lubricating oils, solvents are all collected at different specific temperatures.
What is the method used to separate fractions of crude oil?
Fractional Distillation. Performed in a fractionating column. Heat is applied to the crude oil and it vaporises. Fractions with different boiling points rise to specific heights within the fractionating column, where they are condensed and extracted.
How is it possible to separate crude oil substances?
Through a process known as fractional distillation, also called cracking.The oil is heated and vapours of the various components are given off. The different vapours condense at different temperatures and these fractions are collected.
What is used to separate different fractions in crude oil?
Fractional distillation is used to separate different fractions in crude oil. This process takes advantage of the different boiling points of the components in crude oil to isolate and collect them as they vaporize at specific temperatures.
What is a process where a substance is heated evaporated and cooled in a collection chamber and the different fractions of crude oil distill at different temperatures?
Distillation
Why can crude oil be separated using fractional distillation?
Crude oil can be separated using fractional distillation because its different components have different boiling points. By heating the crude oil and allowing it to vaporize, then condensing the vapor at different temperatures, the various fractions (like gasoline, diesel, and kerosene) can be collected separately based on their boiling points.
Explain how the different chemical compounds in crude oil are separated?
Crude oil is separated into different chemical compounds through a process called fractional distillation. This process involves heating the crude oil to high temperatures, then cooling it in a fractionating column. The different compounds in crude oil have different boiling points, allowing them to be separated based on their molecular size and weight.
Describe how the fractional distillation of crude oil works?
Fractional distillation of crude oil involves heating the oil in a fractionating column and then allowing it to vaporize. As the vapor rises through the column, it condenses at different temperatures based on the boiling points of its components, leading to the separation of various fractions such as gasoline, diesel, and bitumen. The separated fractions can then be collected at different levels of the column for further processing.
What is the method of separation for crude oil?
Crude oil is separated through a process called fractional distillation. It involves heating the crude oil to separate it into different components based on their boiling points. The different fractions, like gasoline and diesel, are then collected at different stages of the distillation tower.
What is the Important of cracking?
The importance of cracking is REALLY important ! Due to the presence of the hydrocarbon atoms present in the fossil fuels, the importance is really beneficial for the people who work in the petroleum industry. As a result of this, the fractions of crude oil are collected at different temperatures as biodegradable polymers. =]
