At what temperature is the root mean square velocity of gaseous hydrogen molecules is equal to that of oxygen molecules at `47^(@)C`? |
|
Answer» Let `T` be the desired temperature. As rms speed of `H_(2)` mol = rms speed of oxygen mol `:. Sqrt((3RT_(H))/(M_H)) = sqrt((3RT_("oxy"))/(M_("oxy")))` or, `(T_H)/(2) = (273 + 47)/(32) , T_(H) = (320)/(16) = 20 K`. |
