Interpretation: To find the new pressure for a sample of nitrogen sealed in a container.
Concept Introduction: According to Gay-Lussac’s law, the pressure of a given mass of a gas varies directly with the absolute temperature of the gas when the volume is kept constant. Mathematically it is written as
Answer to Problem 81A
115 kPa
Explanation of Solution
Given the pressure
The initial temperature
The final temperature
Now, the final pressure has to be determined.
Therefore, the new pressure is equal to
This law clearly explains that the volumes of the reacting gases are small whole numbers when measured at the same temperature and pressure. In this case, the volume is kept constant while the pressure and the temperature will vary.
