| Abstract: | The thermodynamic properties and electrical conductivity of mercury vapor have been calculated for temperatures between 1000°K and 15,000°K and pressures between atmospheric and 10−4 atm. The thermodynamic properties were determined by the methods of statistical mechanics. Account has been taken of the lowering of the ionization potential due to local electric fields and the number of terms employed in the electronic partition function has been limited in accordance with the theory of Ecker and Weizel. The electrical conductivity was computed on the basis of “free path” kinetic theory. It is shown that in the presence of a magnetic field the conductivity has directional properties. For a field of 10,000 G the change in conductivity is illustrated for a particular case. |
