If the absolute temperature of a gas is increased 5 times, the r.m.s. velocity of the gas molecules will be

Options

  1. A5 times
  2. B10 times
  3. C25 times
  4. D5 times

Correct answer

D. 5 times

Step-by-step solution

The mean kinetic energy 1 2 ~m ^2 of the gas molecule is proportional to the temperature T : 2 T v ₂ v ₁ = T ₂ ~T ₁ v ₂ = 5 v ₁
