The root mean square speed of the molecu...

The root mean square speed of the molecules of a diatomic gas is v. When the temperature is doubled, the molecules dissociates into two atoms. The new root mean square speed of the atom is

A

`sqrt2v`

B

v

C

2v

D

4v

Text Solution

Verified by Experts

The correct Answer is:
C
As `v_(rms) prop sqrt(T/M)`
`v._(rms) prop sqrt((2T)/(M//2)) prop v._(rms)=2v_(rms)`
