$STATEMENT-2$ The molecules of a gas collide with each other and the velocities of the molecules change due to the collision.
(Take $\gamma$ for nitrogen and $CO_2$ as $1.4$ and $1.3$ respectively)
$c_P - c_V = a$ for hydrogen gas
$c_P - c_V = b$ for nitrogen gas
The correct relation between $a$ and $b$ is
