Question

Which gas condenses first in fractional distillation of air?

Answer 1

Air is the commercial source for many of the gases it contains. It is separated into its components by fractional distillation of liquefied air. Before air is liquefied, water vapor and carbon dioxide are removed, because these substances solidify when cooled and would clog the pipes of the air liquefaction plant.

Answer 2

ANSWER = Nitrogen is first product obtained of fractional distillation of air
