Current Question (ID: 8206)

Question:

At lower temperature, all gases except $\text{H}_2$ and He show:

Options:

1. Negative deviation
2. Positive deviation
3. Positive and negative deviation
4. None of the above

Solution:

Hint: The positive and negative deviation is determined with the help of the compressibility factor.\n\nExplanation:\n\n$\text{H}_2$ and He shows $PV>RT$; Rest all shows negative deviation.\n\nPositive deviation means volume increase, which is the result of a repulsive force, this indicates that it cannot liquified easily.\n\n-ve means, the volume got decreased due to attractive force, so becomes easier to liquify. Except for $\text{H}_2$, He, other gases show -ve deviations.
