As the temperature is raised from 20ºC to 40ºC, the average kinetic energy of neon atoms changes by a factor of which of the following ?
A.1/2
C.313/293✓ Correct
D.2
Explanation
We know that, kinetic energy per mole= 3RT/2 40 40 40 3 . 2 At C RT K E And 20 20 20 3 . 2 At C RT K E Therefore, 40 20 40 20 . / . / K E K E T T = 273 40 / 273 20 = 313/293.
