Two flask A and B have equal volumes, A is maintained at 300K and B at 600K, while A containes H_(2) gas, B has an equal mass of CO_(2) gas. Find the ratio of total translation kinetic energy of gases in flask A to that of B

Answer»

`1:2`
`11:1`
`33:2`
`55:7`

Solution :`K.E.=(3)/(2)nRT`
`((K.E.)_(A))/((K.E.)_(B))=((3)/(2)n_(A)RT_(A))/((3)/(2)n_(B)RT_(B))=((x)/(2)xx300)/((x)/(44)XX600)`
`=11:1`
