The rms speed of a gas molecule is directly proportional to (A) its absolute temperature (B) the square root of its absolute temperature (C) the square of its absolute temperature (D) its molar mass. |

Answer» Correct Option is (B) the square root of its absolute temperature We know that , root mean square velocity \(V_{rms} = \sqrt \frac{3RT}{M}\) where, R = Gas constant T = absolute temperature M = Molecular mass in kg/mole (B) the square root of its absolute temperature |
