Title
A Calculation of Critical Constants of Metal Gas by using New State Equation of Gas from Liquid Theory
김원수 Won Soo Kim
Abstract
A new state equation of gas derived from liquid theory has been applied to calculate critical constants of metal gases. The parameters a and b of new equation were obtained by using the values of heat of vaporization and collision diameter. The equilibrium volumes of gas and liquid can be calculated from the equation of state. No adjustable parameters, which exhibit different values for different substances, are involved in the calculation. The calculated critical constants of alkali metal gases are then compared with the observed values. The calculated constants of various metal gases which do not have experimental values were compared with the results of Grosse showing a good agreement with each other.
