Two boxes are at the same temperature. The first box contains gas with molecular mass m₁ and rms speed v₁ . The second box contains gas with molecular mass m ₂ and average speed v ₂ . If v ₁=1.5 v ₂ , then m ₁ ~m ₂ is

Options

  1. A1.25
  2. B0.74
  3. C0.52
  4. D0.26

Correct answer

C. 0.52

Step-by-step solution

As V₁=1.5 ~V ₂ aligned & 3 RT m ₁ = 8 RT m ₂ 1.5 & 3 ~m ₁ = 8 1 ~m ₂ 2.25 aligned m ₁ ~m ₂ = 3 2.25 8 =0.52
