Question
A gas has a volume of V cm^3 at 10°C. If the pressure is doubled, at what temperature will the volume still be V cm^3?
Answer: D
💡 Solution & Explanation
Since the volume remains constant at V cm^3, Gay-Lussac's law applies: P1 / T1 = P2 / T2. Given: T1 = 10 + 273 = 283 K, P2 = 2 * P1. P1 / 283 = 2 * P1 / T2 => T2 = 283 * 2 = 566 K. Converting to Celsius: t2 = 566 - 273 = 293°C.
