What is the relationship between pressure and volume in an ideal gas according to Boyle's Law?.
- A.P1V1 = P2V2
- B.PV = nRT
- C.P = V / nRT
- D.PV = constant
Model answer
What a good answer should say
- P1V1 = P2V2
Explanation
Why this works
Boyle's Law states that for a given mass of gas at constant temperature, the product of pressure and volume is constant (P1V1 = P2V2). This relationship shows how pressure decreases as volume increases.
