Question

Out of the following gases under similar condition of temperature and pressure, the velocity of sound will be maximum in (A) hydrogen (B) nitrogen (C) oxygen (D) chlorine

Tardigrade Admin · Accepted Answer

Velocity of the sound in gas v = √(&gamma; RT/M) where the symbols have their usual meanings. All the given gases are diatomic and are at same temperature, ∴ v propto (1/√M)

Q. Out of the following gases under similar condition of temperature and pressure, the velocity of sound will be maximum in

hydrogen

nitrogen

oxygen

chlorine

Velocity of the sound in gas
$v = \frac{γ RT}{M}$
where the symbols have their usual meanings.
All the given gases are diatomic and are at same temperature,
$∴ v \propto \frac{1}{M}$

Q. Out of the following gases under similar condition of temperature and pressure, the velocity of sound will be maximum in

hydrogen

nitrogen

oxygen

chlorine

Velocity of the sound in gas v=MγRT​​ where the symbols have their usual meanings. All the given gases are diatomic and are at same temperature, ∴v∝M​1​
