The temperature of an ideal gas is increased from 27^ C to 127^ C , then percentage increase in v _ rms is

Options

  1. A37 %
  2. B11 %
  3. C33 %
  4. D15.5 %

Correct answer

D. 15.5 %

Step-by-step solution

We know, V _ mms = 3 RT M % increase in array l V _ rms = 3 R T ₂ M - 3 RT ₁ M 3 RT ₁ M 100 = T ₂ - T ₁ T ₁ 100 = 400 - 300 300 100 = 20-17.32 17.32 100=15.5 % array
