  • Real gases behave as ideal gases most closely at low pressure and high temperature. Intermolecular force between ideal gas molecules is assumed to be zero.

    A
    If both Assertion and Reason are true and the reason is correct explanation of the Assertion.
    B
    If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
    C
