If temperature of gas molecules is raised from 127^ C to 527^ C , the ratio of r.m.s. speed of the molecules is respectively

Options

  1. A1: 2
  2. B2: 1
  3. C1: 2
  4. D2: 2

Correct answer

C. 1: 2

Step-by-step solution

We know V_ rms = 3 R T m The temperature of the same gas molecule is raised. V _ mm T The ratio of the velocities is aligned & V ₁ ~V ₂ = T ₁ T ₂ & V ₁ ~V ₂ = 400 800 & V ₁ ~V ₂ = 1 2 aligned
