Question

Real gases behave like ideal gas at:
  1. A
    High pressure and low temperature
  2. B
    Low pressure and high temperature
    Correct
  3. C
    STP always
  4. D
    Only for noble gases

Correct answer

Low pressure and high temperature

Explanation

At low P: molecules are far apart (intermolecular forces negligible). At high T: thermal KE >> intermolecular PE. Both conditions approximate ideal behaviour.
