The speed of sound in oxygen at S.T.P. will be approximately: (Given, R = 8 . 3 J K - 1 , γ = 1 . 4 )

Options

  1. A310 m s - 1
  2. B333 m s - 1
  3. C341 m s - 1
  4. D325 m s - 1

Correct answer

A. 310 m s - 1

Step-by-step solution

The speed of sound is given by, v = γ R T M = 1 . 4 × 8 . 3 × 273 32 × 10 - 3 = 314 . 8541 ≃ 315 m s - 1 Nearest answer given in the option is 310 m s - 1 .
