If masses of all the molecules of a gas are halved and their speeds are doubled, then the ratio of initial and final pressures is
Text Solution
Verified by ExpertsThe correct answer is:
A
1 : 2
Using the relation 
...(i)
and also 
...(ii)
Dividing Eq.(ii) by Eq. (i), we get
So, p : p' = 1 : 2
The ratio of initial and final pressures is 1 : 2.
