Results and discussion

Melting / freezing point
Melting / freezing pt.:
ca. -121.1 °C

Any other information on results incl. tables

Three successive tests were retained.

Mean onset for melting occurred at -121.1 °C ± 0.1 °C. The validity criteria were fulfilled: the standard deviation within the three replicate assessments did not exceed 0.5 °C.

Reference material: ethanol. Nominal onset for boiling = 78.2 ± 0.5 °C. Measured onset = 78.3 °C.
