Answer : The pressure after the temperature change is, 0.752 atm
Explanation :
Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.

or,

where,
= initial pressure = 0.82 atm
= final pressure = ?
= initial temperature = 
= final temperature = 
Now put all the given values in the above equation, we get:


Thus, the pressure after the temperature change is, 0.752 atm
