Speed of Sound in Gases

The velocity of sound is directly proportional to the square root of the molecular mass of the gas.

Two mono atomic ideal gases are having molecular masses $20$ and $30$ respectively. They are enclosed at same temperature using separate containers. The ratio of the speed of sound in gas $1$ to that in gas $2$ is $\sqrt{\frac{2}{3}}$.

Consider two mono atomic ideal gases $1$ and $2$. They are having molecular masses ${\text{M}}_{\text{1}}$ and ${\text{M}}_{\text{2}}$respectively. They are enclosed at same temperature using separate containers. What is the ratio of the speed of sound in gas $1$ to that in gas $2$?

The velocity of sound is independent of the molecular mass of the gas.

Will the velocity of sound depend upon the molecular mass of the gas?

Why the sound waves travel faster in solids and liquids than gases?

A tuning fork sends out waves of wavelength 68.75 cm and 3 m in air and hydrogen gas respectively. If the velocity of sound in air is 330 m s^-1, find the velocity of sound in hydrogen. Also, find the frequency of the tuning fork

A student plotted the following four graphs representing the variation of velocity of sound in a gas (at constant temperature) with the pressure$P$. Which one is correct?

The pressure wave, $P=0.01\sin \left[1000t-3x\right]\mathrm{N}\mathrm{ }{\mathrm{m}}^{–2}$ , corresponds to the sound produced by a vibrating blade on a day when atmospheric temperature is $0°\mathrm{C}$ . On some other day when temperature is $T$ , the speed of sound produced by the same blade and at the same frequency is found to be $336\mathrm{ }\mathrm{m}\mathrm{ }{\mathrm{s}}^{–1}$ . Approximate value of $T$ is:

Estimate the speed of sound in air at standard temperature and pressure. The mass of $1$ mole of air is $29.0\times {10}^{-3} \mathrm{kg}$.

Higher humidity of air means _____ saturation.

The velocity of sound in hydrogen at $0°\mathrm{C}$ is $1200 \mathrm{m} {\mathrm{s}}^{-1}.$ When some amount of oxygen is mixed with hydrogen, the velocity decreases to $500 \mathrm{m} {\mathrm{s}}^{-1}.$ Given that the density of oxygen is $16$ times that of hydrogen. The ratio of ${\mathrm{H}}_2$ to ${\mathrm{O}}_2$ by volume in this mixture is $n$. The value of integer just before $n$ is
