Which law relates the pressure; volume; temperature; and moles of an ideal gas in a single equation?
Difficulty: Medium
About this MCQ
Medium MCAT item. Correct choice: A. Ideal Gas Law (PV = nRT).
- A. Ideal Gas Law (PV = nRT) ✓
- B. Boyle's Law
Why not B: “Boyle's Law” is not Ideal Gas Law (PV = nRT).
- C. Charles's Law
Why not C: “Charles's Law” is not Ideal Gas Law (PV = nRT).
- D. Dalton's Law
Why not D: “Dalton's Law” is not Ideal Gas Law (PV = nRT).
Correct answer
A. Ideal Gas Law (PV = nRT)
Explanation
Ideal Gas Law (PV = nRT) is the term that matches “Which law relates the pressure; volume; temperature; and moles of an ideal gas in a single equation” (option A). Option B (Boyle's Law) is a different value from Ideal Gas Law (PV = nRT). Option C (Charles's Law) is a different value from Ideal Gas Law (PV = nRT). Option D (Dalton's Law) is a different value from Ideal Gas Law (PV = nRT). Keep Ideal Gas Law (PV = nRT) as the MCAT fact for this stem.
