Key Points
- Vapor Pressure: The vapor pressure of nitrogen increases significantly with temperature, reaching high pressures at higher temperatures.
- Critical Point: At temperatures above the critical temperature of nitrogen, it cannot be liquefied by pressure alone.
- Cryogenics: Liquid nitrogen is widely used in cryogenic applications due to its low boiling point.
- Inert Gas: Nitrogen is used in various industries as an inert gas to prevent oxidation and other reactions.
