Which of the following statements is true for Boyle's law?.
- A.P1V1 = P2V2
- B.P1V1 = nRT
- C.V1/T1 = V2/T2
- D.P1/T1 = P2/T2
Model answer
What a good answer should say
- P1V1 = P2V2.
Explanation
Why this works
Formula/rule: P1V1 = P2V2. Substitution: The product of pressure and volume remains constant.
Working: P1V1 = P2V2. Answer: P1V1 = P2V2.
Units/Conclusion: No units required; this is the fundamental expression of Boyle's law.
