<u>Answer:</u> The new pressure will be 101.46 kPa.
<u>Explanation:</u>
To calculate the new pressure, we use the equation given by Gay-Lussac Law. This law states that pressure is directly proportional to the temperature of the gas at constant volume.
The equation given by this law is:

where,
are initial pressure and temperature.
are final pressure and temperature.
We are given:
By using conversion factor: 

Putting values in above equation, we get:

Hence, the new pressure will be 101.46 kPa.
