Industries use the gas for cutting, welding and melting metals.

As liquid oxygen, it burns spacecraft fuel.

Of all the uses of oxygen, sustaining life is the most important. Oxygen is needed by all living organisms. Through a process known as aerobic respiration, energy from food is generated. This allows humans and animals to perform their daily activities.

These polymers are used to create fabrics and plastics. Oxygen can also be found in tanks in aircraft and submerge vessel. Scientific researchers use the oxygen-18 and oxygen-16 isotopes in fossils to determine Earth’s climate millennia ago. It is also used in water treatment and chemical combustion.
