Yes. Air can be separated through fractional distillation. The air must be cooled to a liquid first. Considering nitrogen oxygen and argon all have different boiling points, the liquid air mixture can be heated very gently and carefully in a fractionating column. Each element will eventually vaporise and they can be condensed and collected at different points up the fractionating column because they each have different boiling points.
Bc it’s raining and the temperature goes to freezing or below then the rain can turn into snow and typically temperature decreases naturally at night (or evening in this case)
