Oxygen (O) is a chemical element. In nature, oxygen is a gas with no color or smell. Oxygen is a very important element because we need it to live. It is a part of the air people breathe and the water people drink. Many living things (including humans) need oxygen to live and breathe, though it is poisonous to some forms of life. In liquid state of matter, oxygen is light blue.
Oxygen is what makes burning possible. This is called combustion. When an object or something burns, oxygen combines with another substance and releases heat and light. For instance, when wood burns, the oxygen in air combines with the wood to create fire. This ability of oxygen has many uses. But it also makes pure oxygen very dangerous. If pure oxygen touches a flame or spark, it can make a hot fire and cause great damage. Combustion is used in many ways.
When oxygen is mixed with acetylene, it can create a very hot flame. This is used in welding, where metal is heated and melted together. Also, oxygen is used to create powerful propellants for rockets.Oxygen can be used in smelting metal from ore.Oxygen is used in hospitals for killing bacteria. It is also used when a patient has had carbon monoxide poisoning.Oxygen is used in water treatment to purify the water to make it safe to drink.People with certain illnesses are less sick when they breathe pure oxygen.
Water contains oxygen. When one oxygen atom combines with two hydrogen atoms, they form a molecule of water (also written as H2O). This water is required by all living things to live.
Air also contains oxygen. Air is made of many gases that are mixed together. Approximately 21% of the air is oxygen. Oxygen is especially important because all animals use oxygen to get energy from their food.
Pure oxygen can be produced in several ways. In nature, plants produce oxygen by using sunlight, carbon dioxide (another gas) and water. This process is called photosynthesis. Most of the oxygen in the air is produced by photosynthesis.
People mostly get pure oxygen from air by separating it from nitrogen. Oxygen can also be produced by electrolysis.
