Real gases deviate more from ideal behavior at :
Correct answer: C. High pressure and low temperature
- A. High temperature only
- B. High pressure only
- C. High pressure and low temperature
- D. Low pressure and high temperature
Explanation
High pressure and low temperature: Both high pressure and low temperature amplify intermolecular forces, leading to greater deviations from ideal behavior. The reduced kinetic energy and increased proximity of gas particles result in stronger attractive forces, impacting gas behavior.

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.
