At the same temperature and pressure, the densities of two diatomic gases are 
and 
, respectively. The ratio of mean kinetic energy per molecule of gases will be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
At a given temperature ( 
), all the ideal gas molecules, no matter what their masses, have the same average translational kinetic energy.
i.e. 
So, 
does not depend on density. ( 
Mass 
)
