Industrially, oxygen is extracted from air through fractional distillation, a process that separates gases based on their different boiling points. States of Matter and Phase Transitions The matter type of O2 is not static; it can transition between solid, liquid, and gas depending on temperature and pressure.
O2 Molecule vs Air Composition: Understanding the Matter Type of O2
Classification as a Pure Substance and Element Oxygen gas (O2) is classified as a pure substance because it has a fixed composition and consistent properties throughout the sample. At extremely low temperatures, oxygen condenses into a pale blue liquid, which is highly paramagnetic and used in industrial applications.
It is a reactant, not a fuel, acting as an oxidizing agent that enables the release of stored chemical energy. The classification of O2 as a gaseous matter type is vital for designing storage systems, such as high-pressure tanks or cryogenic containers, ensuring safe handling and transport.

The Role in Environmental and Industrial Contexts The gaseous nature of O2 is crucial for its role in the environment. Further cooling leads to a solid state, forming a crystalline structure that exists at temperatures below -218 degrees Celsius.
