The root mean square speed of the molecules of a diatomic gas is v. When the temperature is doubled, the molecules dissociate into two atoms. The new root mean square speed of the atom is
A
B
v
C
2v
D
4v
Text Solution
Verified by ExpertsThe correct answer is:
C
. According to problem T will becomes T /2 and M will becomes M /2 so the value of 
will increase by 
times i.e. new root mean square velocity will be 2 v .
