Imagine a planet whose diameter and mass are both one half of those of earth. The day's temperature of this planet surface reaches upto `800 K`. ? Make calculation and tell whether oxygen molecules are possible in the atmosohere of the planet.
[Escape velocity from earth's surface `= 11.2 km//s, k = 1.38 xx 10^(-23)J//K`, mass of oxygen molecule `= 5.3 xx 10^(-26) kg`].

Answer

Oxygen molecules connot escape
