If at the same temperature and pressure,...

If at the same temperature and pressure, the densities of two diatomic gases are `d_(1)` and `d_(2)` respectively. The ratio of mean kinetic energy permolecule of gasses will be

A

`1 : 1`

B

` d_1 : d_2`

C

` sqrt(d_1) : sqrt(d_2)`

D

` sqrt(d_2) : sqrt(d_1)`

Text Solution

Verified by Experts

At a given temperature (T) all the ideal gas molecule no matter what their masses, have the same translational kinetic energy
` E = (3)/(2) KT`
So , E does not depend upon density
` (E_1)/(E_2) =(1)/(1)`
