AIt is directly proportional to it
BIt is unrelated to the pressure
CIt is inversely proportional to it
DIt is equal to the square of it
Answer & Solution
Correct answer: C. It is inversely proportional to it
1. Pushing the plunger of a sealed syringe squeezes the gas into a smaller volume and its pressure climbs.
2. Pulling the plunger out enlarges the volume and the pressure falls.
3. If the volume rises by some factor, the pressure falls by that same factor, so the product of pressure and volume stays constant.
4. That is inverse proportionality, written P1V1 equals P2V2.
