Abstract

Possibilities for realization of the sublimation temperature point (–78.464 °C) of carbon dioxide at standard atmospheric pressure are investigated. A simple methodology is demonstrated, and experimental results consistent with those obtained by other authors who used much more sophisticated methods are presented.
