The r.m.s. speed of hydrogen at S.T.P. is '$u$' $\text{m/s}$. If the gas is heated at constant pressure till its volume becomes three times, the final temperature of the gas and the r.m.s. speed are respectively

$1092\ \text{K}$ , $3u\ \text{m/s}$

$1092\ \text{K}$ , $\dfrac{u}{3}\ \text{m/s}$

$819\ \text{K}$ , $\sqrt{3}\,u\ \text{m/s}$

$819\ \text{K}$ , $\dfrac{u}{\sqrt{3}}\ \text{m/s}$
