Question 2 • GA-GSE Physical Science A

Which statement best describes Gay-Lussac’s law?

Answer
A
Pressure is inversely proportional to volume.
B
Pressure is inversely proportional to temperature.
C
Pressure is directly proportional to volume.
D
Pressure is directly proportional to temperature.

Explanation

Gay-Lussac’s law states that for a fixed amount of gas at constant volume, pressure is directly proportional to absolute temperature. As the temperature increases, the pressure increases in the same proportion. Therefore, the correct statement is “Pressure is directly proportional to temperature.”
