The ratio of kinetic energy of a diatomic gas molecule at a high temperature to that of NTP is

Options

  1. A3 2
  2. B5 3
  3. C5 7
  4. D7 5

Correct answer

D. 7 5

Step-by-step solution

The kinetic energy of a gas molecule is K = K E / molecule = f 2 k _ B ~T For diatomic gas, f₁=7 (At high temperature) f ₂=5 (At low temperature) k ₁ k ₂ = f ₁ f ₂ = 7 5
