Q1 · Difficulty 1/3
Which of the following correctly states Boyle's Law for a fixed mass of gas at constant temperature?
- Pressure is directly proportional to volume
- Pressure is inversely proportional to volume
- Pressure is directly proportional to temperature
- Volume is inversely proportional to temperature
Show answer & explanation
✓ Answer: B — Pressure is inversely proportional to volume
Boyle's Law states that for a fixed mass of gas at constant temperature, pressure is inversely proportional to volume (P ∝ 1/V). This means that as pressure increases, volume decreases by the same factor. Options A, C, and D describe incorrect relationships.
