Two vessel A and B in volume ratio 2 : 1 maintained at temperature 300 K and 600 K contain equal mass of `CH_(4)` and `O_(2)` respectively. The ratio of toal translational kinetic energy of gas in flask A to that of flask B is -

Options

A. 1
B. 2
C. 4
D. 0.25

Answer

A

Explanation

`(KE_(A))/(KE_(B)) = ((3)/(2) xx n_(CH_(4)) RT_(A))/((3)/(2) xx n_(O_(2))RT_(B))`
`((w)/(16) xx 300)/((w)/(32) xx 600) = (1)/(1)`
