JEE · NEET Previous Year Question

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

Topic: JEE PYQ

Answer: A. Full step-by-step solution below.

A $310 m / s$
B $333 m / s$
C $341 m / s$
D $325 m / s$

Correct answer: A

Solution

(a) v = m \frac{γRT}{M} = \frac{1.4 \times 8.3 \times 273}{32 \times 10 ^{- 3}} = 314.8541 ≃ 315 m / s
