* Air is a mixture of gases. The most abundant are nitrogen (N2) and oxygen (O2), with smaller amounts of argon (Ar), carbon dioxide (CO2), and others.
* Condensation is the process where a gas changes into a liquid. This happens when the temperature of the gas drops below its boiling point.
* Boiling points vary widely between gases.
At -200°C (-328°F), the following will *not* condense:
1. Helium (He): Helium has the lowest boiling point of all elements (-268.9 °C or -452 °F). It will remain a gas even at extremely low temperatures.
2. Neon (Ne): Neon has a boiling point of -246.08 °C (-410.9 °F). It will also remain a gas at -200 °C.
Important Note: While the other gases in air would likely condense at -200°C, this is an extremely low temperature. You would need specialized equipment to reach this temperature.
