Question:
Consider the following:
Statement I: Real gases exhibit ideal behaviour at high pressures and low temperatures.
Statement II: At high pressure, all gases have compressibility factor (Z) either as 1 or< 1.
Consider the following:

Statement II: At high pressure, all gases have compressibility factor (Z) either as 1 or< 1.
Statement I: Real gases exhibit ideal behaviour at high pressures and low temperatures.
Statement II: At high pressure, all gases have compressibility factor (Z) either as 1 or< 1.
Show Hint
Real gases show deviation from ideal behavior especially at high pressure and low temperature due to intermolecular interactions.

- Both statement-I and statement-II are correct
- Both statement-I and statement-II are not correct
- Statement-I is correct, but statement-II is not correct
- Statement-I is not correct, but statement-II is correct
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
- Statement I is incorrect: Real gases do **not** behave ideally at high pressure and low temperature — they deviate more significantly.
- Statement II is incorrect: At high pressures, the compressibility factor \( Z \) can be greater than 1 (due to repulsive forces), not just ≤1.
