fractional distillation
this is a liquid with the lowest boiling point
The liquid with the lowest boiling point will be the first to be collected in fractional distillation. This is because it vaporizes at a lower temperature and rises first in the fractionating column before condensing.

What does fractional distillation rely on?
Fractional distillation relies on the differences in boiling points of the components in a mixture. By heating the mixture to a specific temperature, the component with the lowest boiling point will vaporize first and can be collected, leaving behind the higher boiling point components in the distillation flask.
What comes out first in fractional distillation of petroleum?
Lighter fractions, such as gases and gasoline, come out first in fractional distillation of petroleum because they have lower boiling points. As the temperature increases, heavier fractions like diesel and lubricating oils are collected.
How is Xenon manufactured?
Xenon is typically obtained as a byproduct during the fractional distillation of liquid air. The air is first cooled and liquefied, then slowly warmed up to allow different components to vaporize at their specific boiling points. Xenon, having a high boiling point, separates out during this process and is collected as a gas.
How do you separate water alcohol and acetone?
To separate water, alcohol, and acetone, you can use fractional distillation. First, heat the mixture to vaporize the acetone, which has the lowest boiling point. Then cool and condense the acetone vapor, which can be collected separately. Next, heat the remaining liquid to vaporize the alcohol, which has a higher boiling point than acetone but lower than water. Finally, separate water from the mixture by distilling the remaining liquid, as water has the highest boiling point of the three compounds.
How is pure nitrogen obtained from air?
Pure nitrogen can be obtained from air through a process called fractional distillation. This process involves cooling air to extremely low temperatures to liquefy it, then allowing it to warm up slowly while collecting the different components as they evaporate at different temperatures. Nitrogen will evaporate first, allowing it to be collected as a pure gas.
Why does nitrogen boils first during fractional distillation of liquid air?
Oxygen is the first to boil.

What separates distillation?
Distillation separates components in a liquid mixture based on their different boiling points. When the liquid is heated, the component with the lower boiling point vaporizes first and is collected separately from the higher boiling point components.
What is the difference between simple distillation and fractional distillation?
Simple distillation refers to the "simple" separation of a solid and a liquid by evaporating the liquid and collecting it after it passes through a condenser to be changed into a liquid state. Fractional distillation refers to the more complex way of separation, usually involving a liquid/liquid mixture (eg. ethanol and water). these can be separated since they both have different boiling points. When this mixture is heated the ethanol having the lowest boiling point boils off first, followed by the water. However the fractional coulomb condenses both gases back into liquid, and fall back in the flask, with time the ethanol gains enough energy to over come the fractional coulomb (this happen before the water does this since ethanol has a LOWER boiling point) and pass through the condenser, changes into a liquid and is collected.
What substance is removed at the filtration stage during the fractional distillation of air?
First the components or the gases in the air are liquefied(made into liquid)under low temperature and high pressure.Then it is passed through the fractionating column.Gases evaporate there.Then the gases can be obtained.
Where should such an opening be in simple distillation?
The opening in simple distillation should be located at the top of the distillation apparatus, where the vapor is collected and condensed back into liquid form. This allows for the separation of components based on their boiling points, with the lower boiling point component vaporizing first and being collected through the opening.
How is pure argon made?
Pure argon is typically produced through the fractional distillation of liquid air. In this process, air is first liquefied and then slowly warmed up, causing the various components of air to vaporize at different temperatures. Since argon has a boiling point of -185.7°C, it vaporizes before other components, allowing it to be separated and collected as a pure gas.
How do we separate petrol oil from crude oil?
First of all there is a fractional distillation column, cold up top hot on bottom, with levels where the vapors can go up but not down. It is heated on the bottom. So when a substance in the vapor reaches a height where the temperature of the 'barrel' is equal to that substance's boiling point, it will condense to form a liquid and collected. It is called fractional distillation. a pic here will help you understand. http://www.msm.cam.ac.uk/doitpoms/tlplib/recycling-polymers/figurescrude_oil_distillation_sml.jpg
