Velocity of sound in oxygen at STP is V. Then the velocity of sound in hydrogen at STP is\

Question

Professor PC Thomas Classes · Answer

$\mathrm{V}=\sqrt{\frac{\gamma \mathrm{RT}}{\mathrm{M}}}$ For oxygen $\mathrm{M}=32$\ $	herefore \mathrm{V}=\sqrt{\frac{\gamma \mathrm{RT}}{32}}$\ For hydrogen $\mathrm{M}=2$\ $	herefore \mathrm{V}_{	ext {hydrogen }}=\sqrt{\frac{\gamma \mathrm{RT}}{2}}$\ Divide and get the result.\
