Behaviour of Real Gases

The pressure exerted by 1 mole of CO₂ at 273 K, is 34.98 atm. Assuming that volume occupied by CO₂ molecules is negligible, the value of van der Waals' constant for attraction of CO₂ gas is :

In Van der Waal’s equation of state for a non-ideal gas, the term that accounts for intermolecular forces is:

Van der Waal’s real gas, act as an ideal gas, at which conditions ?

At which one of the following temperature – pressure conditions the deviation of a gas from ideal behaviour is expected to be minimum ?

When deviation is more in the behaviour of a gas from the ideal gas equation PV = nRT ?

An ideal gas can’t be liquefied because

Gases deviate from ideal behaviour at high pressures because the gas molecules
