This is a constant-volume heating problem—a direct application of Gay-Lussac's Law. Since the container is rigid, volume stays fixed, so pressure and absolute temperature are directly proportional. You just need to set up the ratio of final to initial pressure using the ideal gas law, where $PV=nRT$ simplifies beautifully when $V$, $n$, and $R$ are constant.
