Abstract

(1) A common error in text-books on physical chemistry is pointed out. It is hoped that the correct value for the triple point temperature, +.0098° C, will be given in new books and in succeeding editions of the books surveyed above.

(2) Inconsistencies in the vapor pressure values for ice and for liquid water near 0° C are pointed out.

(3) The equilibrium vapor pressures for ice and liquid water under two different sets of equilibrium conditions are compared with the triple point pressure.
