   Is nitrogen a gas at room temperature?

   • and is a gas at room temperature. is made up of 78% nitrogen. The next most common gas is oxygen, at 21%. Nitrogen isn't very reactive, but it can react with oxygen at high temperatures, such as in car engines. These reactions make nitrogen oxides. The boiling point of nitrogen is −196 °C, so liquid nitrogen is very cold indeed.

   • The Discovery of Nitrogen. Daniel Rutherford discovered nitrogen in 1772. He was a Scottish chemist and a physician with a passion for understanding gases, and he owed his discovery to a mouse.
   • Nitrogen in Nature. Nitrogen is a part of all plant and animal proteins. The nitrogen cycle is a pathway in nature that transforms nitrogen into usable forms.
   • Everyday Uses for Nitrogen. You may regularly consume traces of nitrogen because it's often used to preserve foods, particularly those that are prepacked for sale or sold in bulk.
   • Nitrogen as a Greenhouse Gas. Compounds of nitrogen, and particularly nitrogen oxides NOx, are considered greenhouse gases. Nitrogen is used as a fertilizer in soils, as an ingredient in industrial processes, and is released during the burning of fossil fuels.
