Real gases show ideal behavior at_______?
Correct answer: B. High Temp & Low Pressure
- A. Low Temp & High Pressure
- B. High Temp & Low Pressure
- C. High Temp & High pressure
- D. Low Temp & Low Pressure
Explanation
Real gases approach ideal behaviour at high temperature and low pressure because attractive forces and molecular volume become relatively insignificant. At low temperature or high pressure, intermolecular attractions and particle volume cause greater deviation, so option a is the likely trap.

About Real and Ideal Gases
An ideal gas is modelled as particles with negligible volume and no intermolecular attraction, obeying Boyle's, Charles's and Avogadro's laws through PV = nRT. Real gases deviate from this behaviour, especially at high pressure and low temperature, because particle volume and attractive forces matter; the van der Waals equation explains these corrections.
