fractional distillation of liquefied air

Question 1

what is the first step to separating liquefied air?

Answer 1

air is first cooled and compressed via the cooler. solid carbon dioxide and water are removed

Question 2

what is the second step to separating liquefied air?

Answer 2

liquid air is then separated into its constituents or fractions via fractional distillation in a fractionating column. the gases are separated due to differences in their boiling points.

Question 3

how are gases in the fractionating column ordered?

Answer 3

gases which have the lowest boiling point, is distilled over at the top as it is more volatile and has a higher tendency to convert back to gas
