Ethane freezing point
Webfreezing temperature of ethane has an average freezing point of 87.59 K (with error). Methane, however, re-mains liquid down to at least 86 K. Nitrogen dissolu-tion suppresses the freezing temperatures of these liq-uids. Nitrogen, however, is considerably more soluble in methane than ethane [5, 6, 7] and, therefore has a temperature of me-.
