It has a triple point at 83.7 K and 0.68 atm. [12][13] An unreactive gas was suspected to be a component of air by Henry Cavendish in 1785.[14]. Liquid argon molecules confined in silver and graphite nano-channels are examined separately. Unlike most substances, water is denser as a liquid than as a solid. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). Lori M. Answer. This article is about the chemical element. Argon may be used as the carrier gas in gas chromatography and in electrospray ionization mass spectrometry; it is the gas of choice for the plasma used in ICP spectroscopy. [38], Argon is sometimes used for extinguishing fires where valuable equipment may be damaged by water or foam.[39]. Sort the following compounds by chemical reaction rate. They operated the arc until no more reduction of volume of the gas could be seen for at least an hour or two and the spectral lines of nitrogen disappeared when the gas was examined. Sublimation Argon is preferable to the helium that had been used in the preceding five decades, because helium gas escapes through the intermolecular pores in most containers and must be regularly replaced.[45]. The water pressure off the gases in the bulb is 1.17 ADM from We have the pressure off neon from the previous result. Identify the correct statement(s) about argon's density in different phases.
