At Given Temperature Rms Velocity Of Molecules Of Gas Is Proportional To Molecular Weight

At a given temperature the rms velocity of molecules of the gas is (A) Proportional to … (D) Proportional to square of…

Answers:

The correct option (C) Inversely proportional to square root of molecular weight.

 Explanation:

Vrms = √(3RT/Mo)

  i.e.  Vrms ∝ (1/√Mo)

Hence rms velocity is inversely proportional to square root of molecules weight.
