Gas-filled tube - Wikipedia
Mercury mixed with an inert gas is used where the energy losses in the tube have to be low and the tube lifetime should be long. In mercury-inert gas mixtures, the discharge is initially carried primarily by the inert gas; the released heat then serves to evaporate enough mercury to reach the desired vapor pressure.
They produce light when an electric current passes between two electrodes (also called cathodes) in a tube filled with low-pressure mercury vapor and inert gases, such as argon and krypton.
The very accurate measurements of the vapor pressure of mercury by Ambrose and Sprake [18] were made with an ebulliometric technique. The transpiration method (also called gas saturation) involves passing a steady stream of an inert gas over or through the sample, which is held at constant temperature.
Noble gas - Wikipedia
The noble gases (historically the inert gases, sometimes referred to as aerogens[1]) are the members of group 18 of the periodic table: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn) and, in some cases, oganesson (Og).
Inert gas - Wikipedia
An inert gas is a gas that does not readily undergo chemical reactions with other chemical substances and therefore does not readily form chemical compounds. Though inert gases have a variety of applications, they are generally used to prevent unwanted chemical reactions with the oxygen (oxidation) and moisture (hydrolysis) in the air from ...
The formation of weakly bound molecules mercury-inert gas and …
An attempt has been made to describe the violet side bands occurring in the 2537 Å (1 S 0 − 3 P 1) mercury resonance line perturbed by inert gases, measured in absorption in terms of weakly bound molecules Hg-inert gas.
Is Mercury inert - Answers
Jun 3, 2024 · Mercury isn't very reactive but it is in no way chemically inert. It reacts with sulphur fairly readily and so sulphur is used to treat Mercury spills. It reacts with oxygen to make the...
What Chemicals Make Up Mercury's Atmosphere? - Sciencing
Apr 24, 2017 · Data shows that Mercury has carbon dioxide, nitrogen and other familiar gases, although in very small total amounts. According to the Messenger findings, carbon dioxide gas makes up over 95 percent of Mercury's atmosphere.
Down the Tubes - How Fluorescent Lamps Work | HowStuffWorks
The tube contains a small bit of mercury and an inert gas, typically argon, kept under very low pressure. The tube also contains a phosphor powder, coated along the inside of the glass.
Nov 1, 2010 · After a reaction/equilibration time of 1.5 to 2 minutes, the inert gas or air is turned on, sweeping the atomic mer- cury out of the reaction vessel and into the open-ended quartz tube aligned in the optical path of the AA instrument.
