The ratio of speed of sound in hydrogen gas to the speed of sound in oxygen gas at the same temperature is:

Options

  1. A4: 1
  2. B1: 2
  3. C1: 4
  4. D1: 1

Correct answer

A. 4: 1

Step-by-step solution

Given M _ H ₂ =2 ; M _ O ₂ =32 Speed of sound, v = RT M v 1 M v _ H ₂ v _ O ₂ = M _ O ₂ M _ H ₂ = 32 2 =4: 1
