Explain why (a) velocity of sound is generally greater in solids than in gases, (b) the velocity of sound in oxygen is lesser than in hydrogen. At the same temperature the speed of sound in oxygen is lower than in hydrogen because:

Options:

Answer:

Solution:

$v = γ RT / M$ . $M$ for oxygen is 32 and for hydrogen 2, with the same $γ = 1.4$ , so $v$ is lower for oxygen.
