Through a process called liquefaction, air condenses and becomes liquid at cryogenic temperature. DISTILLATION OF AIR. By slowly warming up the liquid air, distillation separates air into its different component gases. Nitrogen is separated first (boiling point -196°C), then Argon (boiling point -186°C), and Oxygen last (boiling point …
