In distillation you boil off the substance you want ... then re-condense it.
In fractional distillation you boil up a mixture of original substance ...
and tap off the "steam" (the vapor) at various levels (thus different temperatures) and so you get different substances at each tap.
It is most commonly used for crude oil to get many products.

What is the effect of sugar and salt in the evaporation of water?
the water iwll evaporate leaving the salt and sugar then seperatee this using fractional distilation
What is it called when a acid reacts with an alkali?
distilation
How is petroleum separated and the fractional parts collected?
fractional distillation
How do you turn nitrogen from a gas to a liquid?
in general you need to two things: But Liquid Nitrogen is not made this way. 1st it needs to be cooled very cold. Then it needs to be compressed. The proccess usually does this both at the same time, Cooled Nitrogen is run through a compressor and then cooled agian, and then super cooled to create Liquid. It is produced using a proccess called fractional distilation of air resulting in Liquid Oxegen and Liquid Nitrogen.
Which type of bonding is broken in fractional distilation?
Fractional distillation doesn't involve a chemical change.
How do you get different fuels from oil?
thru fractional distilation of the oil
Which distilation is used to convert rectifired spirit into absolute alcohal?
fractional ditilation
Why is it difficult to obtain 100 percent oxygen from fractional distilation?
It forms an azeotrope.
Why are fractional distilation useful?
This process helped us to separate ex-specially for crude oil.
How alkanes are produced?

What is the effect of sugar and salt in the evaporation of water?
the water iwll evaporate leaving the salt and sugar then seperatee this using fractional distilation
How you separate two immiscible liquid?
I am guessing by fractional distilation because they should have diffrent boiling point but if the boiling points are the same then add salt to make them impurities and have diff boiling points then do fractional distillation
How can fuel oil be changed into petrol?
by fractional distilation which is heating something up so it boils and evaporates then the petrol condences and runs down the tube for petrol it turns into petrol (from fuel oil) by catylistic cracking, this is when the hydrocarbon get chopped of into smaller pieces
What are some examples of distilation?
distillation of water
