Find the temperature at which oxygen molecules would have the same rms speed as of hydrogen molecules at `300 K`.A. 600 KB. 2400 KC. 1200 KD. 4800 K

Answer» Correct Answer - D
`C_("oxy") = sqrt((3RT_(OXY))/(M_(OXY))) = C_(H) = sqrt((3RT_(H))/(M_(H)))`
`:. (T_(OXY))/(M_(OXY)) = (T_H)/(M_H)`
`:. T_(OXY) = (T_H)/(M_H) xx M_(OXY) = (300 xx 32)/(2) = 4800K`.
