An ideal gas of molar mass ' M ₀ ' has r.m.s. velocity ' V ' at temperature ' T '. Then

Options

  1. AVT ^2= constant
  2. BV ^2 ~T = constant
  3. CV ^2 ~T = constant
  4. DV is independent of T

Correct answer

B. V ^2 ~T = constant

Step-by-step solution

R.M.S. velocity is given by aligned & V = 3 R T M ₀ & V ^2= 3 RT M ₀ & V ^2 ~T = 3 R M ₀ = constant aligned
