If an ideal gas at 100 K is heated to 109 K in a rigid container, the pressure increases by X%. What is the value of X?

Answer

9

Explanation

V , n constant.
`(P_(i))/(T_(i))=(P_(f))/(T_(f))implies P_(f)=( T_(f))/(T_(i))P_(i)=((109)/(100))P_(i)`
`impliesP_("increases")/_\P=P_(f)-P_(i)=(9)/(100)P_(i)`
`:.` Pressure increases
`=(/_\P_(f))/(P_(i))xx100=(9P_(i))/(100P_(i))xx100%`
`X%=9%`
`X=9`
