Mercury definition: a heavy, silver-white, highly toxic metallic element, the only one that is liquid at room temperature; quicksilver: used in barometers, thermometers, pesticides, pharmaceutical preparations, reflecting surfaces of mirrors, and dental
1.a heavy, silver-white, toxic metallic element, liquid at room temperature: used in barometers, thermometers, pesticides, pharmaceuticals, mirror surfaces, and as a laboratory catalyst; quicksilver.Symbol:Hg;at. wt.:200.59;at. no.:80;sp. gr.:13.546 at 20°C;freezing point:−38.9°C;boil...
Mercury usually available in liquid state; in normal condition, it is only the few metallic element that remains in liquid state at room temperature. Mercury is the poor conductor of heat, but it is a good conductor of the electricity. The freezing point of mercury is −38.830C and the ...
It has a freezing point of −38.83 °C and a boiling point of 356.73 °C,[10][11][12] both the lowest of any stable metal, although preliminary experiments on copernicium and flerovium have indicated that they have even lower boiling points.[13] This effect is due to lanthanide contract...
Since the freezing point of mercury is -38.83 degrees Celsius, instruments containing the metal are rendered useless in the Arctic and Antarctic regions, where the lowest recorded temperature is around -70 °C.

2) Mercury has a freezing point of−38.83oCand a boiling point of356.73oC. 3) Although preliminary experiments on copernicium and flerovium have shown that they have even lower boiling points. On the freezing, the volume of mercury decreases by 3.59% of its original and its density changes ...
The Greek name for it washydrargyros"liquid silver," which gives the element its symbol,Hg. Comparequicksilver, which is its popular name. It has a freezing point of -39° C. The use of the word in reference to temperature or state of the atmosphere (by 1756) is from its use in the...
This vertical stratification along with a less biologically active central Arctic (i.e., lower reduction capacity; point (2)) could explain why ocean Hg evasion is limited north of the MIZ. GEM measurements performed during a poleward transect in early August during the MOSAiC expedition support...
One end of the strand is cooled to below the solidification point (freezing point) with the aid of Peltier elements (13, 13'). Subsequently, a solidified strand element of predetermined length is cut off by means of an impact die (14) and is flung downwards, passing through the pump ...
