Initially, the root mean square (rms) velocity of $\displaystyle \mathrm{N}_2$ molecules at certain temperature is $\displaystyle u$. If this temperature is doubled and all the nitrogen molecules dissociate into nitrogen atoms, then the new rms velocity will be :
Official answer
(2)
$\displaystyle 2 u$
