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

`sqrt(313//293)`

B

`1//2`

C

`313//293`

D

`2`

Text Solution

Verified by Experts

The correct Answer is:
C
According to the kinetic molecular theory of gases , we have
Kinetic energy (KE) per mole =` (3)/(2) RT`
i.e., `KE prop T`
Thus, `(KE_(2))/(KE_(1)) = (T_(2))/(T_(1)) = (40 + 273)/(40 + 273) = (313)/(293)`
