How to calculate the valence of sulfate ion
0
Usually, the boiling point of liquid oxygen is -183°C, the boiling point of liquid nitrogen is -196°C, and the boiling point of liquid helium is -268.9°C. As the temperature rises, the first thing that separates
The first to separate is helium.
At temperatures below -268.9 degrees, all three gases are liquid
When the temperature rises to -268.9 degrees, helium changes from liquid to gas and separates first
When the temperature rises to -196°C, liquid nitrogen becomes gaseous and separated
When the temperature rises to -183 degrees, the liquid oxygen becomes gaseous and finally separated
