Among the following, the incorrect statement is :
Show Hint
- At low pressure, real gases show ideal behaviour.
- At very low temperature, real gases show ideal behaviour.
- At very large volume, real gases show ideal behaviour.
- At Boyle's temperature, real gases show ideal behaviour.
The Correct Option is B
Solution and Explanation
Statements (1) and (3) are correct (low pressure means large volume). At the Boyle temperature, \(Z \approx 1\) over a wide range of pressure, so (4) is acceptable.
At very low temperature, intermolecular attractions dominate and gases deviate strongly from ideality (they liquefy), so (2) is incorrect.
Answer: (2) At very low temperature, real gases show ideal behaviour.

Top JEE Main Questions
- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
