Q. Statement A: Gases deviate from their ideal behaviour at low temperatures.
Statement B: At low temperatures, the molecular attractions become significant. This leads to a deviation from the ideal behaviour of a gas.

Q. Real gases show deviations from ideal gas law because molecules interact with each other. At high pressures molecules of gases are very close to each other. At very low temperatures intermolecular forces become significant. The deviation from ideal gas behaviour can be measured in terms of compressibility factor

Z

, which is the ratio of product

P V

n R T

Z = P V / n R T

) . Taking the pressure and volume corrections due to intermolecular forces vander waals corrected the ideal gas equation.
In vander waals equation of state for non ideal gases, the term that accounts for intermolecular forces

Q. In the following statements:
(A) Ideal gases are liquefied only at very low temperatures.
(B) Ideal gases cannot be liquefied.
(C) Ideal gas behaviour is observed by real gases at low pressures.
(D) Ideal gases do not exist.
The correct statements are:

Under which of the following conditions applied together, a gas deviates most from the ideal hevaviour?
