- B.Pressure is inversely proportional to volume.
- C.Pressure is independent of volume.
- D.Pressure equals volume.
Model answer
What a good answer should say
- Pressure is inversely proportional to volume.
Explanation
Why this works
The relationship between pressure and volume in an ideal gas at constant temperature is described by Boyle's Law, which states that pressure is inversely proportional to volume. This means that as volume decreases, pressure increases, and vice versa.
The implication is that understanding this relationship is crucial for predicting gas behavior under changing conditions.
