A rigid nitrogen tank stored inside a laboratory has a pressure of 30 atm at 06:00 am when the temperature is 27°C. At 03:00 pm, when the temperature is 45°C, the pressure in the tank will be ______ atm. [nearest integer]

1. 32.00
2. 32.00
3. 32.00
4. 32.00

Correct answer: 32.00

Solution

The pressure of a gas is directly proportional to its temperature when the volume is constant, according to Gay-Lussac's law. As the temperature increases from 27°C to 45°C, the pressure also increases, resulting in a calculated pressure of approximately 32 atm.
