A vessel of volume V contains a mixture of 1 mole of Hydrogen and 1 mole of Oxygen (both considered as ideal). Let \(f_1(v)dv\), denote the fraction of molecules with speed between \(v\) and (v + dv) with \((v+dv)\), similarly for oxygen. Then \(f_2(v)dv\), similarly for oxygen. Then
1. \(f_1(v)+f_2(v)=f(v)\) obeys the Maxwell's distribution law
2. \(f_1(v), f_2(v)\) will obey the Maxwell’s distribution law separately
3. Neither \(f_1(v)\), nor \(f_2(v)\) will obey the Maxwell’s distribution law.
4. \(f_2(v)\) and \(f_1(v)\) will be the same
