The rms velocity of hydrogen is $\sqrt{7}$times the rms velocity of nitrogen. If T is the temperature of the gas [IIT 2000]

(1) $T\left({H}_{2}\right)=T\left({N}_{2}\right)$

(2) $T\left({H}_{2}\right)>T\left({N}_{2}\right)$

(3) $T\left({H}_{2}\right)

(4) $T\left({H}_{2}\right)=\sqrt{7}T\left({N}_{2}\right)$
