Thermodynamics. Will give Credit. Thanks for your help

Critical properties of a gas are P = 20 MPa and T = 150 K. Can the gas be assumed to ideal gas at 20 Mpa and 150 K? Yes No because ideal gas law P is not low enough and T is not high enough because ideal gas law P and T are too high

Solution

Option C

As per given gas conditions , the gas cannot assumed as Ideal gas because its pressure is too much high relative to critical pressure and its temperature is too much low relative to critical temperature , at these condition gas possessing intermolecular attractions among gas molecules which makes the gas to deviate from IDEAL Behaviour
