Gas because a solid is very tightly packed, liquid is a little bit less packed, and a gas is very free.
it is inert, our air contains nitrogen more than any other gas
No, nitrogen gas (N2) contains two nitrogen atoms.
The atmosphere contains more nitrogen than oxygen. Approximately 78% of the atmosphere is nitrogen, while oxygen makes up about 21%. The remaining 1% consists of other gases like argon, carbon dioxide, and trace gases.
Nitrogen monoxide (NO) has a higher ionization energy compared to nitrogen gas (N2) because NO has one fewer electron in its outer shell, making it easier to remove that electron.
Nitrogen is a diatomic gas at room temperature. These nitrogen atoms are bond by a triple bond. It needs more energy to break this bond. So nitrogen is less reactive.
Higher temperatures mean more heat energy which translates into more kinetic energy of the molecules of nitrogen gas. This greater kinetic energy allows the molecules to diffuse faster than at a lower temperature and lower kinetic energy.
Nitrogen Gas
Yes, when enough energy is removed from nitrogen gas, it can transition from a gas to a liquid state at extremely low temperatures (around -196 degrees Celsius). This process is known as liquefaction.
Air contains approximately 78% nitrogen gas.
Nitrogen gas (N2) is relatively inactive and contains a triple bond between the two nitrogen atoms. Triple bonds are stronger than double or single bonds, making it difficult for nitrogen gas to react with other molecules.
Overall, natural gas is a cleaner burning fuel than coal. Coal contains a lot of ash compared to gas which creates a lot of particulate matter pollution (think soot). Additionally, coal contains sulfur and nitrogen compounds which when burned form sulfur dioxide and nitrogen oxides, both of which are gaseous air pollutants that lead to the formation of acid rain. Natural gas does consist of nitrogen too, so you have to be aware of minimizing nitrogen oxides as well when using it. But technology exists in the burners inside the boiler that minimize the formation of nitrogen oxides when burning natural gas.
Nitrogen is preferred for unclogging gas lines because it is an inert gas that poses less risk of combustion compared to compressed air, which contains oxygen and can create a fire hazard in a gas line. Nitrogen is also less likely to react with the substances in the gas line, ensuring a more effective and safe unclogging process.
