    No, because the escape speed for such a planet would be much lower than for Earth.
     No, because no planet could get up to such a high average temperature.
     No, since the average molecular speed for oxygen would be above Earths escape speed..
     Yes, because the escape speed for such a planet would be much higher than for Earth.
     Yes, since the average molecular speed for oxygen would still be below Earths escape speed..
