Abstract:

The vapour pressure of Cd, Mg, Se, Te and Zn, which ranges from a few mm. Hg up to 1 atomospheric pressure, was measured by the boiling point method devised by the present author. The results obtained are shown in Fig. 3. From these data the empirical formulae of the relation between vapour pressure and temperature were determined as follows:
Cd ………… log p=-5660/T+8.32
Mg ………… log p=-9230/T+9.87
Se………… log p=-5531/T+8.58
Te………… log p=-5833/T+7.54
Zn………… log p=-6271/T+8.19
By utilizing the above relations, the latent heat of vaporization and changes of internal energy and entropy glue to vaporization of these metals were calculated and discussed thermo dynamically.
