The equation, PV = nRT, is best obeyed by gases at____________________?
Correct answer: B. Low pressure & high temperature
- A. High pressure & low temperature
- B. Low pressure & high temperature
- C. Low pressure & low temperature
- D. None of these
Explanation
Real gases approach ideal-gas behaviour when intermolecular forces and molecular volume become negligible, which occurs at low pressure and high temperature. High pressure and low temperature promote non-ideal behaviour.
