Physical Properties:
* State: Gas at room temperature and pressure
* Color: Colorless
* Odor: Odorless
* Taste: Tasteless
* Density: 1.2506 kg/m³ at 0 °C and 1 atm
* Melting point: -210.01 °C (-346.02 °F)
* Boiling point: -195.79 °C (-320.42 °F)
* Solubility in water: Very low (0.015 g/L at 20 °C)
* Non-flammable: Does not burn
* Diatomic molecule: Composed of two nitrogen atoms bonded together
Other Important Features:
* Non-reactive: Nitrogen gas is relatively inert and does not readily react with other substances at room temperature.
* Essential for life: Nitrogen is a key component of DNA, RNA, and proteins.
* Major component of the atmosphere: Nitrogen makes up about 78% of Earth's atmosphere by volume.
It's important to note that while nitrogen gas is generally harmless, it can be harmful in high concentrations. For example, in enclosed spaces, nitrogen can displace oxygen, leading to suffocation.
