Molecular Speeds & Maxwell Distribution

The temperature of an ideal gas is increased from 100 K to 400 K. If ' xx ' is the R.M.S. velocity of its molecules at 100 K, it becomes

Show answer and solution

Answer: (b)

  1. vrms∝Tv_{rms} \propto \sqrt{T}
  2. v′x=400100=2\frac{v'}{x} = \sqrt{\frac{400}{100}} = 2
  3. So the answer is (b) 2x2x.
