Question
In the below table the boiling point of a few gases are given. The liquid mixture which contains these all gases are fractionally distilled. What will be the order of gases distilling out?
- Oxygen, Argon, Nitrogen, Neon
- Argon, Neon, Oxygen, Nitrogen
-
Oxygen, Nitrogen, Neon, Argon
- Neon, Nitrogen, Argon. Oxygen
Hint:
First the gas with lower boiling point will separate out and then gradually other gases.
The correct answer is: Neon, Nitrogen, Argon. Oxygen
- Fractional distillation is the separation of a mixture into its component parts, or fractions. Chemical compounds are separated by heating them to a temperature at which one or more fractions of the mixture will vaporize. It uses distillation to fractionate. Generally the component parts have boiling points that differ by less than 25 °C (45 °F) from each other under a pressure of one atmosphere pressure.
- First the gas with lower boiling point will separate out and then gradually other gases.
- The order of gases distilling out are Neon, Nitrogen, Argon. Oxygen respectively.
