Let the r.m.s. velocity of molecule of a given mass of gas be C ₁ at temperature 27^ C . When the temperature is increased to 327^ C , the r . m . s . velocity is C ₂ . Then the ratio C ₂ C ₁ is

Options

  1. A2
  2. B2
  3. C4
  4. D2 2

Correct answer

A. 2

Step-by-step solution

T ₁=27^ C =27^ +273=300 k T ₂=327^ C =327^ +273=600 k C ₂ C ₁ = T ₂ ~T ₁ = 600 300 = 2
