It is eaiser to liquefy oxygen than hydrogen because.

Options

A. Oxygen has a higher critical temperature and lower inversion temperature than hydrogen.
B. Oxygen has a lower critical temperature and higher inversion temperature than hydrogen.
C. Oxygen has a higher critical temperature and higher inversion temperature than hydrogen.
D. The critical temperature and inversion temperature of oxygen is very low.

Explanation

`mu_(rms)(H_(2))=sqrt((T)/(M))=sqrt((50)/(2))=5`
`mu_(rms)` of `O_(2) prop sqrt((T)/(M))=sqrt((800)/(32))=5`
Therefore, the ratio is `1`.
