Gas law check (Gay-Lussac/Amontons law): judge the statement Statement: “For a perfect gas at constant volume, p/T = constant.” Choose whether the statement is correct or incorrect.

Q: Gas law check (Gay-Lussac/Amontons law): judge the statement Statement: “For a perfect gas at constant volume, p/T = constant.” Choose whether the statement is correct or incorrect.

Concept/Approach From the ideal gas equation pV = nRT, with V and n constant, p ∝ T ⇒ p/T = constant. Final Answer Agree — at constant volume, pressure is directly proportional to temperature.

Difficulty: Easy

Agree (the statement is correct)
Disagree (the statement is incorrect)
True only at very low pressures
True only for monatomic gases

Correct Answer: Agree (the statement is correct)

Explanation:

Concept/Approach

From the ideal gas equation pV = nRT, with V and n constant, p ∝ T ⇒ p/T = constant.

Final Answer
Agree — at constant volume, pressure is directly proportional to temperature.
