A Assuming an altitude of 194 metres above mean sea level (the worldwide median altitude of human habitation), an indoor temperature of 23 °C, a dewpoint of 9 °C (40.85% relative humidity), and 760 mmHg sea level–corrected barometric pressure (molar water vapor content = 1.16%). B Calculated values *Derived data by calculation.
Physical property Helium Neon Argon Krypton Xenon Radon; Density, liquid at boiling point and 1 atm (g/dm³) [1]: 125.0: 1207: 1393.9: 2415: 3057: 4400 Density, liquid at triple point (g/dm³) [1]
In monatomic gases (like argon) at room temperature and constant volume, volumetric heat capacities are all very close to 0.5 kJ⋅K −1 ⋅m −3, which is the same as the theoretical value of 3 / 2 RT per kelvin per mole of gas molecules (where R is the gas constant and T is temperature). As noted, the much lower values for gas heat ...
The first stable compound of argon was reported in 2000 when argon fluorohydride (HArF) was formed at a temperature of 40 K (−233.2 °C; −387.7 °F). [ 20 ] In October 2006, scientists from the Joint Institute for Nuclear Research and Lawrence Livermore National Laboratory successfully created synthetically oganesson , the seventh element ...
Small granite pillars have failed under loads that averaged out to about 1.43 ⋅ 10 8 Newtons/meter 2 and this kind of rock has a sonic speed of about 5.6 ± 0.3 ⋅ 10 3 m/sec (stp), a density of about 2.7 g/cm 3 and specific heat ranging from about 0.2 to 0.3 cal/g °C through the temperature interval 100-1000 °C [Stowe pages 41 & 59 and ...

One solid interstitial compound of argon, Ar 1 C 60 is stable at room temperature. Ar 1 C 60 was discovered by the CSIRO. Argon ionises at 15.76 eV, which is higher than hydrogen, but lower than helium, neon or fluorine. [1] Molecules containing argon can be van der Waals molecules held together very weakly by London dispersion forces. Ionic ...
