Kinetic Theory Ques 9
9. The temperature of a gas is raised from $27^{\circ} C$ to $927^{\circ} C$. The root mean square speed is
[1994]
(a) $\sqrt{(927 / 27)}$ times the earlier value
(b) remain the same
(c) gets halved
(d) get doubled

Answer:
Correct Answer: 9.(d)
Solution:
- (d) $v _{rms} \propto \sqrt{T}$
As temperature increases from $300$ $ K$ to $1200$ $ K$ that is four times, so, $v _{\text{rms }}$ will be doubled.
