Question

separating technique of different gases from air​

Answer 1

Answer:

Separation Techniques : Obtaining Gases from Air

Step 1:Conversion of air into liquid air.

Step 2:Fractional Distillation. The liquid air is then passed through the fractional distillation column. Here, the liquid air is allowed to warm-up. The bottom of the fractionating column is warmer than the top.

Answer 2

Answer:

separating different gases from air is called fractional distillation method

Explanation:

the air is a mixture of different gases it contains 21 per oxygen 78 per nitrogen 0.93 argon and 0.38 per carbon and other traces gases

fractional distillation method

fractional distillation is a separation of mixture into its components parts or fractions .chemical compounds are separated by heating them to a temperature at which one or more fractions of mixture will vaporize . it uses distillation to fractionate . generally the component parts have boiling points that different by less than 25 degree Celsius (77 degree f ) from each other under a pressure of one atmosphere . if the difference in boiling points greater than 25 degree Celsius a simple distillation is typically used .
