Chemistry - Ideal Gas Question with Solution | TestHub

The container is closed, so the number of molecules stays $N$: ($C$) is wrong.

At constant $V$ and $n$, $P$ is proportional to the absolute temperature, not the Celsius temperature.

$T_1$ = 300 K, $T_2$ = 327 K, so $P_2$ = $P$ x 327/300 = 1.09 $P$.

Answer: (B).
