When its temperature reaches -195.79°C, liquid nitrogen changes back to a gas. A container can be put into place to catch the nitrogen as it boils off the liquid air. When the temperature reaches -182.96°C, oxy
Nitrogen is the primary gas in the atmosphere. It makes up 78.084 percent by volume in dry air, and that makes it the most common gas in the atmosphere. Its atomic symbol is N and its atomic number is 7. The Discovery of Nitrogen Daniel Rutherforddiscovered nitrogen in 1772. He was a ...
