Argon, discovery

However, the discovery in 1962 by Voronel and coworkers [H] that the constant-volume heat capacity of argon showed a weak divergence at the critical point, had a major impact on uniting fluid criticality widi that of other systems. They thought the divergence was logaritlnnic, but it is not quite that weak, satisfying equation (A2.5.21) with an exponent a now known to be about 0.11. The equation applies both above and... [Pg.641]

Lord Rayleigh (Royal Institution, London) investigations of the densities of the most important gases and for the discovery of argon in connection with these studies. P. Lenard (Kiel) work on cathode rays. [Pg.1300]

Sir William Ramsay (1904, chemistry discovery of the noble gases) Lord John W. Rayleigh (1904, physics argon and density of gases)... [Pg.110]

Strutt was the fourth Baron Rayleigh, son of John William Strutt, the third Baron Rayleigh, with whom Ramsay had collaborated on the discovery of argon. He, like Thomson, ran independent experiments that undermined Ramsay, Collie, and Patterson s results ... [Pg.130]

Sir William Ramsay, 1852-1916. Scottish chemist and physicist. Discoverer of the inert gases. Lord Rayleigh was a co-discoverer of argon, and M. W. Travis collaborated in the discovery of krypton, neon, and xenon. After F. E. Dorn had discovered radon, or radium emanation, Ramsay and Whidaw Gray determined its density and proved it to be the heaviest member of the argon family. [Pg.778]

Professor of physics at Cavendish Laboratory, Cambridge. He made elaborate investigations of the electrochemical equivalent of silver and of the combining volumes and compressibilities of gases. His observation that nitrogen prepared from the atmosphere is heavier than nitrogen prepared from ammonia led to the discovery of argon, the first noble gas. He also contributed to optics and acoustics. [Pg.780]

When the British Association met at Oxford in the same month, Ramsay and Rayleigh astonished the members by announcing the discovery of the first inert gas, which, at the suggestion of Mr. H. G. Madan, the chairman, they proposed to call argon, the lazy one (9, 25, 30). [Pg.784]

Soon after hearing of the discovery of argon, Lecoq de Boisbaudran predicted that it might belong to a family of absolutely inert elements all of which were then unknown, and that their atomic weights would be 20.0945, 36.40 0.08, 84.01 0.20, and 132.71 0.15. He also predicted that the first two of these elements would be more abundant than the others (33, 34). [Pg.785]

Argon is an important element for nucleosynthesis, for the discovery and interpretation of isotopic anomalies, and for the interpretation of the origin of planetary atmospheres. Argon is the eleventh most abundant element in the universe thus it is an important datum for nucleosynthesis theories. It is much rarer in terrestrial abundances because most Ar was lostinto space (owing to its inertness and high volatility) as the Earth formed. [Pg.170]

From this clue came also the later discovery of three other inert elements of the air. From liquid argon, the same scientists separated new neon, hidden krypton, and xenon (the stranger) present to the extent of one part in eighty thousand, twenty million, and one hundred and seventy million parts of air respectively. With modern apparatus at his disposal it is not difficult to believe that Cavendish might have been the discoverer of these noble gases one hundred years before they were given to the world. [Pg.60]
