Similar to argon but duller, more pink; at high peak currents bright blue-white. used in the Moore lamp (historically) Oxygen: Violet to lavender, dimmer than argon: Hydrogen: Lavender at low currents, pink to magenta over 10 mA Water vapor: Similar to hydrogen, dimmer Carbon dioxide: Blue-white to pink, at lower currents brighter than xenon
Ar contamination. Most of the argon in Earth's atmosphere was produced by electron capture of long-lived 40 K (40 K + e − → 40 Ar + ν) present in natural potassium within Earth. The 39 Ar activity in the atmosphere is maintained by cosmogenic production through the knockout reaction 40 Ar (n,2n) 39 Ar and similar reactions. The half-life of 39

Solid argon-hydrogen clathrate (Ar(H 2) 2) has the same crystal structure as the MgZn 2 Laves phase. It forms at pressures between 4.3 and 220 GPa, though Raman measurements suggest that the H 2 molecules in Ar(H 2) 2 dissociate above 175 GPa. A similar Kr(H 2) 4 solid forms at pressures above 5 GPa. It has a face-centered cubic structure where ...

A 175-watt mercury-vapor light approximately 15 seconds after starting. A closeup of a 175-W mercury-vapor lamp. The small diagonal cylinder at the bottom of the arc tube is a resistor which supplies current to the starter electrode. A mercury-vapor lamp is a gas-discharge lamp that uses an electric arc through vaporized mercury to produce ...
Argon (symbol Ar) is the third element in group 18, the noble gases. Argon is the third most common gas in the Earth's atmosphere , at 0.93%, making it more common than carbon dioxide . Nearly all of this argon is radiogenic argon-40 derived from the decay of potassium-40 in the Earth's crust.
The quality of a speaker's soundstage depends not only on the sound that travels in a direct path from the speaker to your ears, but also on the sound that reflects off your walls before you hear it.
