Lesson: Gay-Lussac’s Law Physics • 9th Grade
In this lesson, we will learn how to use the formula P/T = constant (Gay-Lussac’s law) to calculate the pressure or temperature of a gas that is heated or cooled at a constant volume.
Sample Question Videos
For a gas at a constant volume, if the temperature is , then the pressure .
Which of the following is the correct unit for pressure?
A gas has an initial pressure of 500 Pa, a volume of 0.1 m3, and a temperature of 300 K. It is allowed to expand without changing temperature until its volume is 1 m3. Then, the temperature of the gas is increased, while the volume is kept constant, to 360 K. What is the final pressure of the gas?
