Question

Give four uses of oxygen

Answer 1

1) Humans Breathe OxygenEarths mammals, along with many other species, require oxygen to survive. They breathe the gas into their lungs, where the blood absorbsit and sends it to the other cellsin the body where it is used for cellular respiration. This is the process by which oxygen and glucose create chemical energy, water and carbon dioxide, which the species thenexhales back into the atmosphere. Because oxygen is essential for life, humans store it for emergency uses and in places where breathableoxygen does not occur naturally. For instance, airplanes keep a supply of it onhand in case the cabin rapidly depressurizes (if there's a hole in the plane), submarines keep stores of it that the crew may breathe and hospitals offer canisters of it to patients with respiratory issues like lung cancer.2) Oxygen for TransportationWhile airplanes need air to fly, and while oxygen makes up around a fifth of Earth's air, similarly dense gases could, in theory, provide the pressure necessary for flight. That said, other machines make use of oxygen in some form or another to move. Submarines make use of hydrogen peroxide, H2O2when starting their engines; prior to this, subs needed to frequently come to the surface to access atmospheric oxygen. Similarly, some submarine torpedos alsodischarge from these machines using oxygen. Rockets also use liquid oxygenas an oxidizer, rather than as a fuel itself. In short, oxygen works to increase the rate of combustion for rocket fuel. Engines, like the ones in cars, also use oxygen: The element is necessary for combustion.3) Medical Uses of OxygenMany hospitals also keep oxygen in a variety of ways to treat a variety of ailments. Pediatric incubators help provide a safe environment for newborns and infants to develop when they are born prematurely, without the ability to regulate their heat or when they have wounds, to name a few. Doctors regulate the amount of oxygen in these areas as excessive amounts ofit can damage newborns, though it is still a necessary element in these scenarios. Oxygen also finds use in other medical areas: doctors enrich gaseous anaesthetics with it toensure a patient survives, for instance.4) Oxygen Helps Clean Waste WaterIn many cases, water that comes to treatment plants has its oxygen levels depleted. Thisis something of an issue, considering many of the bacteria and other micro-organisms these plants use to break down harmful compounds in the water rely on oxygen to thrive and outproduce competing, potentially dangerous other organisms in the water. Historically, workers at these plants have used atmospheric oxygen to help these benevolent bacteria, but recently they have started using pure oxygen gas, pumping it into the dirty water and enabling them to use smaller containers than when using the atmosphere's oxygencontent to treat the same amount of waste water.
