The speed of sound in oxygen at S.T.P. will be approximately: (Given, $R = 8.3 JK^{- 1}, γ = 1.4)$

Options:

Answer:

Solution:

At STP Temperature, $T = 273 K$ Molecular mass of oxygen, $M = 32 \times 1 0^{- 3} kg$ Speed of sound is given by $v = \frac{γ RT}{M} = \frac{1.4 \times 8.3 \times 273}{32 \times 1 0 ^{- 3}}$ $= 314.8541 ≃ 315 m / s$
