Two flasks A and B have equal volumes. A is maintained at 300 K and B at 600 K. A contains `H_(2)` gas, B has an equal mass of `CO_(2)` gas. Find the ratio of total K.E. of gases in flask A to that of B.

A

`1:2`

B

`11:1`

C

`33:2`

D

`55:7`

Text Solution

Verified by Experts

The correct Answer is:
b
(b) `KE_(T)=(3)/(2)nRT=(3)/(2)(W)/(M)RT`
`KEprop(T)/(M)`
`(KE_(1))/(KE_(2))=(T_(1))/(M_(1))(M_(2))/(T_(2))=(300)/(2)xx(44)/(600)=(11)/(1)`
