Q. As the temperature is raised from $20℃\ to\ 40℃,$ the average kinetic energy of neon atoms changes by a factor of which of the following?
A) 1/2
B) $\sqrt{313/293}$
C) 313/293
D) 2
Explanation
(c)
Average KE $= \frac{3}{2}\ RT/N_{0}$
$(KE) \propto T$
$\therefore(KE)_{313}/(KE)_{293} = \frac{313}{293}$
