View SolutionThe ratio of the speed of sound in helium gas to that in nitrogen gas at the same temperature is $\left(\gamma_{He}=\frac{5}{3}, \gamma_{N_2}=\frac{7}{5}, M_{He}=4, M_{N_2}=28\right)$
At what temperature does the velocity of sound in air increase by $10\%$ compared to its velocity at $0^{\circ}C$ (in $^{\circ}C$)?
Regarding the speed of sound in a gas, match the following:
$A$. Temperature of gas is made $4$ times and pressure $2$ times $P$. Speed becomes $2\sqrt{2}$ times $B$. Only pressure is made $4$ times without change in temperature $Q$. Speed becomes $2$ times $C$. Only temperature is changed to $4$ times $R$. Speed remains unchanged $D$. Molecular mass of the gas is made $4$ times $S$. Speed becomes half
