SATHEE: Kinetic Theory - Result Question 16

Kinetic Theory - Result Question 16

16. 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

(d) get doubled

Show Answer

Answer:

Correct Answer: 16. (d)

Solution:

(d) $v_{r m s} \propto \sqrt{T}$

As temperature increases from $300 K$ to $1200 K$ that is four times, so, $v_{rms}$ will be doubled.
