Van der Waals Equation

Q. In general, real gases behave most ideally at _____ pressures and _____ temperatures. The behavior of real gases can be described using the van der Waals equation [P + (n^2a/V^2)](V-nb) = nRT The values of a and are given below for the two real gases argon and oxygen. The gas in which deviations from ideal behavior due to intermolecular forces are expected to be the smallest is _____. The gas that would be expected to behave least like an ideal gas at high pressures is _____.
