Answer: Gay Lussac's law
The final temperature of the gas will be 275 K.
Step-by-step explanation:
Gay-Lussac's Law: This law states that pressure is directly proportional to the temperature of the gas at constant volume and number of moles.
(At constant volume and number of moles)

where,
= initial pressure of gas = 298 kPa
= final pressure of gas = 325 kPa
= initial temperature of gas = 300 K
= final temperature of gas = ?


Therefore, the final temperature of the gas will be 275 K.
