A product that is free of controversy

The portable type O cylinders are filled with liquefied oxygen. Mostly used for medical purposes or in areas with scarce or no oxygen like under(a) water or at high levels above the background knowledge i.e. aerospace.Medically, oxygen gas is used in the treatment of gas poisoning, pneumonia, used as an anesthetic when blend with nitrous oxide or administered in deficiency of oxygen (Rees, Dudley, 2006).Liquefied oxygen is pale blue in color, and has a density of 1.141g/cm3. The liquid has a boiling point of -182.96oC and a freezing point of -222.65oC. Its raw cloth is oxygen which is obtained from natural transport by a process know as fractional distillation. At 20oC the liquid gas has an expansion rate of 8601 (OLeary, 2000).Fractional distillation is done in a grind with boilers this executes the laborers to work at very cold environments which are highly flammable. Natural air is made up of different gases which has different evaporation or freezing points. The natural ai r is first liquefied to be liquid air which has a mixture of liquid nitrogen and liquid oxygen with boiling points of (-196oC) and (-183oC) respectively.Liquid air is heated to -183oC which oxygen evaporate, its tapped and liquefied again now as Oxygen liquid which is thence packed in high pressure cylinders for distribution. Most of the cylinders meet minimum requirements of weighing 5 pounds and under and usually last up to 5 hours or more ( take-awayoxygen, 2009). The cylinders administer oxygen in pulses through with(predicate) a device know as a conserver which delivers a pulse of oxygen when the user inhales.Ethical considerations of the overlap are the liquefied gas is highly explosive and flammable hence it use for industrial purposes. receivable to its properties of being highly flammable and explosive some people mix it with powdered charcoal to make explosives which are lethal.The product should be produced the way its being done but its distributions should be control led and sold whole to authorized dealers and users to minimize its use to prepare explosives.ReferencesOLeary, D.
