At what temperature will be the oxygen molecules have the same root mean square root mean square speed as hydrogen molecules at 300 K ?A. 1600 KB. 2400 KC. 3200 KD. 4800 K |
Answer» Correct Answer - D Root mean square speed `V(rms)=sqrt((3RT)/(M))rArrTpropM` `(thereforev_("rms"),Rrarr"constant")` `or" " (T_(O_(2)))/(T_(H_(2)))=(M_(O_(2)))/(M_(O_(2)))` `rArr " " (T_(O_(2)))/(300)=(32)/(2)` `rArr "temperature"" "T_(O_(2))=4800K` |
