What is the ratio of gaseous oxygen to liquid oxygen when LOX is vaporized and warmed to ambient temperatures?

When liquid oxygen (LOX) is vaporized and warmed to ambient temperatures, it expands significantly. The correct ratio of gaseous oxygen to liquid oxygen is approximately 862:1. This value reflects the considerable volume increase that occurs during the phase change from liquid to gas.

Liquid oxygen is much denser than its gaseous form, which is why the ratio is so high. When LOX is converted to gas, it occupies a volume that is nearly 862 times greater than the volume it occupied as a liquid. This dramatic expansion is critical to understand for operations involving oxygen, particularly in aviation and military contexts, where precise measurements for safety and efficiency are essential.

The other ratios do not accurately represent the physical properties and behavior of oxygen during vaporization. For instance, 500:1 and 300:1 suggest a different expansion factor that does not correspond with the established scientific understanding of the vaporization process of liquid oxygen.
