What temperature is necessary to liquefy O₂ at 1 atm pressure?

Question

Quizplus · Accepted Answer

Liquid O₂ is produced by separating it from a liquefied air mixture at a temperature below its boiling point (F1F1F1S1F1F1F10183° C or F1F1F1S1F1F1F10297° F). After it is separated from air, the O₂ must be maintained as a liquid by being stored in insulated containers below its boiling point. As long as the temperature does not exceed -183° C, the O₂ will remain liquid at atmospheric pressure. If higher temperatures are needed, higher pressures must be used. If at any time the liquid O₂ exceeds its critical temperature of -118.8° C, it will convert immediately to a gas.
