Normal Boiling Point and Triple Point Temperatures of Neon

Abstract

The normal boiling point and triple point temperatures and the triple point pressure of neon were found to be 27.096 ± 0.001 K and 24.553 ± 0.001 K, and 43332 ± 13 N/m2 [325.02 ± 0.10 mm Hg (0 °C)], respectively. (The temperatures are in terms of the NBS-1955 provisional temperature scale. The figures after the ± symbol indicate estimated uncertainties.) The triple point pressure is in accord with the more recent values, but the normal boiling point and triple point temperatures deviate significantly from those of previous investigators.
