I did an experiment on the boilng point of LOXY under vertical gravity.
The experiment is simple: fill the block chamber with LOXY, increase and decrease the pressure and temperature, stop time, move the cursor to the liquid level of LOXY, and measure the pressure and temperature at that point.
By doing so, we can determine the boiling point of LOXY for a given pressure.
In this experiment, the temperature onset is -273.15 and the pressure onset is -256.
Therefore, we added 273.15 to the boiling point data, and 256 to the pressure data.
(I defined absolute temperature and "absolute pressure" on this.)
The graph are plotted with temperature on the horizontal axis and pressure on the vertical axis.
As a result, it was found that there is a relation Y = AX + B, where Y is the pressure and X is the boiling point.
From the results of the experiments, it was found that the values of A?0.5 and B?200.
Therefore, it was found that the lower side of this line is LOXY and the upper side is OXYG.
This is the case under vertical gravity.
In the case of zero gravity or radical gravity, the result may be different.
