Two flask A and B of equal volumes maintained at temperature `300K` and `700K` contain equal mass of `He(g)` and `N_(2)(g)` respectively. What is the ratio of total translational kinetic energy of gas in flask A to that of flask B ?
A
`1:3`
B
`3:1`
C
`3:49`
D
None of these
Text Solution
Verified by Experts
The correct Answer is:
b
(b) Boles ratio `(n_(He))/(n_(N_(2)))=(w//4)/(w//28)=(7)/(1)` Ratio of translational K.E.`=(n_(He).T_(He))/(n_(N_(2)).T_(N_(2)))` `=(7)/(1)xx(300)/(700)=3:1`
