Which of the following is true for a gas under conditions of very high pressure? O PV > ART, because the real volume of the gas would be more than the ideal volume.
O PV = nRT, because intermolecular forces are considerable at very high pressures.
O PV = nRT, because all gases behave as ideal gases at very high pressures.
O PV
