Real gas is converted to ideal gas at:
Correct answer: D. High temperature, low pressure
- A. Low temperature, high pressure
- B. High temperature, high pressure
- C. Low temperature, low pressure
- D. High temperature, low pressure
Explanation
At high temperatures and low pressure, molecules of a gas are far apart, with minimal forces of attraction between them. This causes real gases to behave much like an ideal gas.

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.
