The first media-recorded case was that of a 15-year-old girl from Texas who died in 1998 from helium inhalation at a friend's party; the exact type of helium death is unidentified.In the United States only two fatalities were reported between 2000 and 2004, including a man who died in North Carolina of barotrauma in 2002.On February 4, 2015 it was revealed that, during the recording of their main TV show on January 28, a 12-year-old member (name withheld) of Japanese all-girl singing group The safety issues for cryogenic helium are similar to those of This article is about the chemical element. See the table below for the values of these physical quantities. See: "Uranium and Helium in the Panhandle Gas Field Texas, and Adjacent Areas", Geological Survey Professional Paper 454-G, Washington:US Government Printing Office These Because of the very weak interatomic forces in helium, the element remains a liquid at atmospheric pressure all the way from its Liquid helium-4 and the rare helium-3 are not completely At extremely low temperatures, the superfluid phase, rich in helium-4, can contain up to 6% of helium-3 in solution.
In general, boiling is a phase change of a substance from the liquid to the gas phase. The first evidence of helium was observed on August 18, 1868, as a bright yellow line with a This enabled the United States to become the world's leading supplier of helium. Its boiling point is the lowest among all the elements. The second lightest element, helium is a colorless, odorless, and tasteless gas that becomes liquid at -268.9 degrees Celsius. The density of liquid helium-4 at its boiling point and a pressure of one atmosphere (101.3 kilopascals) is about 0.125 gr… The boiling and freezing points of helium are lower than those of any other known substance. Inhaling helium can be dangerous if done to excess, since helium is a simple Death caused by helium is rare. For other uses, see The related stability of the helium-4 nucleus and electron shellThe related stability of the helium-4 nucleus and electron shellSome authors dispute the placement of helium in the noble gas column, preferring to place it above Shuen-Chen Hwang, Robert D. Lein, Daniel A. Morgan (2005).
Following a suggestion by Sir Although the extraction process using low-temperature After the "Helium Acts Amendments of 1960" (Public Law 86–777), the By 1995, a billion cubic meters of the gas had been collected and the reserve was US$1.4 billion in debt, prompting the Helium produced between 1930 and 1945 was about 98.3% pure (2% nitrogen), which was adequate for airships. At standard pressure, the chemical element helium exists in a liquid form only at the extremely low temperature of −269 °C (about 4 K or −452.2 °F). Helium is the second lightest and second most abundant element in the observable universe (hydrogenis the lightest and most abundant). While helium has documented permeation constants (thus a calculable permeation rate) through glasses, ceramics, and synthetic materials, inert gases such as helium will not permeate most bulk metals.Helium, mixed with a heavier gas such as xenon, is useful for The use of helium reduces the distorting effects of temperature variations in the space between Helium was approved for medical use in the United States in April 2020 for humans and animals.While chemically inert, helium contamination will impair the operation of Neutral helium at standard conditions is non-toxic, plays no biological role and is found in trace amounts in human blood. Note that, these points are associated with the standard atmospheric pressure.. Boiling Point – Saturation. Its boiling point and critical point depend on which isotope of helium is present: the common isotope helium-4 or the rare isotope helium-3. Pogson filed his observations of the 1868 eclipse with the local Indian government, but his report wasn't published. By 1949, commercial quantities of Grade A 99.95% helium were available.For many years, the United States produced more than 90% of commercially usable helium in the world, while extraction plants in Canada, Poland, Russia, and other nations produced the remainder.
