If the pressure on 100 c.c. of air is halved, then its volume (at the same temperature) would be ______________ c.c?
Correct answer: D. 200
- A. 100
- B. 50
- C. 205
- D. 200
Explanation
At constant temperature, Boyle's law gives P1V1 = P2V2. Halving the pressure therefore doubles the volume: 100 × 2 = 200 cc.
