Vapor pressure mercury

The results support the theory that the volatilized mercury is adsorbed or absorbed by the ash particles as the gas stream cools. Since the mercury concentrations in the stack gases are considerably lower than the theoretical mercury vapor pressure at the observed temperatures,... 

A vacuum system may consist of a diffusion pump and a backing pump, together with bailies, cold traps and isolation valves. The cold trap is essential if a mercury vapor diffusion pump is used and is best filled with liqnid nitrogen ( — 196°C) otherwise, the system will be exposed to the mercury vapor pressure, which is torr at 18CC. 

High-pressure mercury lamps (mercury vapor pressure during operation 10 Pa). 

The following table gives the vapor pressure of mercury in kUo-pascals (100 kPa = 1 bar) from the triple point (234.3156 K) to the critical point (1764 K). The data are generated from the formulation of Huber, Laesecke, and Friend in Reference 1, which is based on a critical evaluation of all the published data on mercury vapor pressure and related thermodynamic properties. The estimated uncertainty in the vapor pressure is ... 

Mercury solubility (Table 6.3) 3 x 10 rng/1 = 2.7 x lO" mole fraction Mercury vapor pressure (25dC) 0.173 Pa Water vapor pressure (25lC) 3.17 x 10 Pa... 

Some safety officials are worried about exposing workers to mercury (M =200.6 g/mol). If the air in a room is saturated with mercury (vapor pressure at 20°C = 0.0012 torr), assuming that the equilibrium between mercury and air obeys Raoult s law,...
