24: Kinetic Theory of Gases
- #7The mean square speed of the molecules of a gas at absolute temperature T is proportional to
(a)
1T
(b)
T
(c) T
(d) T2.digAnsr: cAns : Root mean squared velocity is given by
`` {v}_{rms}=\sqrt{\frac{3RT}{M}}``
`` \Rightarrow {\left({v}_{rms}\right)}^{2}=\frac{3RT}{M}``
`` \Rightarrow {\left({v}_{rms}\right)}^{2}\alpha T``
Thus,
(c) is the correct answer.
