To answer the question "Oxygen is denser than air, so it is collected over...", we need to analyze the properties of oxygen and the methods of gas collection.1. Understanding the Density of Oxygen: - Oxygen (O2) has a densit
Today, patients can use oxygen (O2) concentrators, which continuously filter nitrogen out of the ambient air in order to supply an oxygen-rich gas stream to the user. Oxygen concentrators are considered a safer, more convenient, and more cost-effective alternative to tanks of oxygen or pressuriz...
. Vapors from liquefied gas are initially heavier than air and spread along ground. Runoff may create fire or explosion hazard. Containers may explode when heated. Ruptured cylinders may rocket. /Oxygen; Oxygen, compressed; Oxygen, refrigerated liquid (cryogenic liquid)//GUIDE 122: GASES - ...

Oxygen itself is nonflammable, but at concentrations greater than 25% supports and vigorously accelerates the combustion of flammable materials. Some materials (including metals) that are noncombustible in air will burn in the presence of oxygen. Fire Hazard Behavior in Fire: Increases intensity of ...
(Oxygen had been discovered a few years before by Joseph Priestley in 1774, and he had called the gas dephlogisticated air.) The same publication also introduced the French words that were soon adopted into English as hydrogen and sodium chloride (common salt), among other terms commonly ...
