Answer: The liquid oxygen machine is producing less liquid oxygen than normal because there's a low attraction between the molecules.
It should be noted that oxygen in its liquid state will take up less space. It can also be stored at a lower pressure than when it's in its gaseous state.
Step-by-step explanation:
From the complete question, the liquid oxygen evaporates at a slightly higher The reason for this is due to the fact that they have similarly low attraction between molecules.
