Oxygen and methane can coexist as liquids at cryogenic temperatures, a property utilized in aerospace propellants and studied in vapor-liquid equilibrium thermodynamics.

The analysis

The retrieved papers examine cryogenic fluid and vapor-liquid equilibria of oxygen-methane mixtures (e.g. Papers 1, 3, and 6), establishing that liquid oxygen and methane are handled and modeled together at low temperatures. Therefore, the claim is supported.
