As the temperature is raised from 20^(@)...

As the temperature is raised from `20^(@)C` to `40^(@)C` the averge kinetic energy of neon atoms changes by a factor .

A

`1//2`

B

`sqrt(313//293)`

C

313/293

D

2

Text Solution

Verified by Experts

The correct Answer is:
C
For monoatomic neon atoms, `E(3)/(2)RT`
`:. (E_(40.))/(E_(20.))=(T_(40.))/(T_(20.))=(40+273)/(20+273)=(313)/(293)`.
