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

To solve the question of why it is easier to liquefy oxygen than hydrogen, we need to understand the concepts of critical temperature and inversion temperature.

### Step-by-Step Solution:

1. **Understanding Critical Temperature**:
- The critical temperature is the temperature above which a substance cannot exist in the liquid state, regardless of the pressure applied. For a gas to be liquefied, it must be cooled below its critical temperature.

2. **Understanding Inversion Temperature**:
...
