The ratio of speed of sound in hydrogen gas to the speed of sound in oxygen gas at the same temperature is:

Options:

Answer:

Solution:

Given $M_{H_{2}} = 2; M_{O_{2}} = 32$
Speed of sound, $v = \frac{γ RT}{M}$
$\Rightarrow v \propto \frac{1}{M}$
$∴ \frac{v _{H_{2}}}{v _{O_{2}}} = \frac{M _{O_{2}}}{M _{H_{2}}} = \frac{32}{2} = 4 : 1$
