24: Kinetic Theory of Gases
- #5Which of the following gases has maximum rms speed at a given temperature?
(a) hydrogen
(b) nitrogen
(c) oxygen
(d) carbon dioxide.digAnsr: aAns : The rms speed of a gas is given by ​`` \sqrt{\frac{3RT}{{M}_{o}}}``.
Since hydrogen has the lowest Mo compared to other molecules, it will have the highest rms speed.
Thus,
(a) is the correct answer.
