The argon phase diagram shows the phase behavior with changes in temperature and pressure. It also shows the saturation pressure with changes in temperature. Theoretical calculation predicts several more argon compounds that should be stable[11] but have not yet been synthesized. Argon compounds - Wikipedia For liquids, the value has to be measured because it certainly Helmenstine, Anne Marie, Ph.D. (2020, August 27). Sketch the phase diagram for argon. Characteristics A small piece of rapidly melting solid argon Argon has approximately the same solubility in water as oxygen and is 2.5 times more soluble in water than nitrogen. Argon is mostly used as an inert shielding gas in welding and other high-temperature industrial processes where ordinarily unreactive substances become reactive; for example, an argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning. Compressed argon gas is allowed to expand, to cool the seeker heads of some versions of the AIM-9 Sidewinder missile and other missiles that use cooled thermal seeker heads. 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. Covalent radiusHalf of the distance between two atoms within a single covalent bond. [50], Argon-39, with a half-life of 269 years, has been used for a number of applications, primarily ice core and ground water dating. Specific heat capacity is the amount of energy needed to change the temperature of a kilogram of a substance by 1 K. A measure of the stiffness of a substance.
