Which of the following is true about pressures in flasks `A` and `B`?A. The pressure in flask `A` is four times that in flask `B`.B. The pressure in flask `B` is four times that in flask `A`.C. Both flasks have some pressure.D. The pressure in flask `A` is eight times that in flask `B`.

Answer» `P_(A)V=n_(A)RT_(A)`, `P_(B)V=n_(B)RT_(B)`
`(P_(A))/(P_(B))=(n_(A)T_(A))/(n_(A)T_(B))=8xx(300)/(600)=4`
`n_(A)=(m)/(2)`, `n_(B)=(m)/(16)`, `(n_(A))/(n_(B))=8`
