If the temperature is raised by 1   K from 300   K , the percentage change in the speed of sound in the gaseous mixture is [ R = 8 . 314   J   mol - 1   K - 1 ]

Options

  1. A0.167 %
  2. B0.334 %
  3. C1 %
  4. D2 %

Correct answer

A. 0.167 %

Step-by-step solution

From v = γ R T M ∆ v v = 1 2 ∆ T T ∆ v v × 100 = 1 2 ∆ T T × 100 = 1 2 × 1 300 × 100 = 0.167 %
