Explanation: A phase diagram is a graphical representation with axes, representing temperature and pressure, showing the equilibrium conditions of a given substance to be a solid, liquid, or gas. Ramsay wrote to Rayleigh suggesting that he should look for a heavier gas in the nitrogen got from air, while Rayleigh should look for a lighter gas in that from ammonia. A 1994 incident, in which a man was asphyxiated after entering an argon-filled section of oil pipe under construction in Alaska, highlights the dangers of argon tank leakage in confined spaces and emphasizes the need for proper use, storage and handling.[52]. points) What ix ECX 42)? Argon was first isolated from air in 1894 by Lord Rayleigh and Sir William Ramsay at University College London by removing oxygen, carbon dioxide, water, and nitrogen from a sample of clean air. [51], Although argon is non-toxic, it is 38% more dense than air and therefore considered a dangerous asphyxiant in closed areas. The argon phase diagram shows the phase behavior with changes in temperature and pressure. Sublimation The arrangements of electrons above the last (closed shell) noble gas. So when a team is 760 tour So the reason why I'm playing in toward because afterwards they're saying it's critical pressure isn't is 2.55 tours, so I just converted into tours.
