Expert Solution
Step 1

Gay-Lussac's law: The relation between pressure and temperature at constant valume was found by Joseph Louis Gay-Lussac in 1808. According to the law, for a given mass and constant volume of an ideal gas, the pressure exerted on the sides of its container by the Gas is directly proportional to its absolute temperature.

                 P ∝ T 

                 P/T = constant

Since the stopper in the question Also a restriction for change in valume hence one can appl this law to the question.
