At what temperature is the root mean square velocity of gaseous hydrog

1.	At what temperature is the root mean square velocity of gaseous hydrogen molecules is equal to that of oxygen molecules at `47^(@)C`?A. `20 k`B. `80 K`C. `- 73 K`D. `3 K`
Answer» Correct Answer - A `(v_(rms))_(H_(2)) = (v_(rms))_(O_(2))` `sqrt((3RT_(H_(2)))/((M_(0))_(H_(2)))) = sqrt((3 R T_(O_(2)))/((M_(0))_(O_(2))))` `sqrt(T_(H_(2))/(2)) = sqrt(((273 + 47))/(32))` `T_(H_(2)) = 20 K`
