Critical Pressure (Pc) for CO2 =72.5ba, O2=49.45bar, N2=33.3bar
Critical Temperature (Tc) CO2=304.3K, O2=154.4K, N2=126.1K
Any gas cannot exist in liquid state when they are cooled below their critical temperature and compressed more then their critical pressure.
As all these gases are not below their critical temperature therefore all are gases at given temperature, despite O2 and N2 has more pressure then its critical pressure but to liquify its temperature should be less then critical temperature.
