Real gases approach ideal behaviour at___________________?
Correct answer: B. Low pressure & high temperature
- A. High pressure & high temperature
- B. Low pressure & high temperature
- C. High pressure & low temperature
- D. Low pressure & low temperature
Explanation
At low pressure, molecules are far apart and intermolecular forces contribute little to the behaviour; high temperature also reduces the relative effect of attraction. Hence real gases most closely approach ideal behaviour at low pressure and high temperature.
