Question

The rms velocity of hydrogen is $\sqrt{7}$ times the rms velocity of nitrogen. If $T$ is the temperature of the gas, then :

(A) $T_{\left(H_{2}\right)}=T_{\left(N_{2}\right)}$

(B) $T_{\left(H_{2}\right)}>T_{\left(N_{2}\right)}$

(C) $T_{\left(H_{2}\right)}<T_{\left(N_{2}\right)}$

(D) $T_{\left(H_{2}\right)}=\sqrt{7} T_{\left(N_{2}\right)}$

Answer 1

If $T$ is the temperature of the gas, then $T_{\left(H_{2}\right)}<T_{\left(N_{2}\right)}$. So, The correct option of this question will be (C).
