Answer: Option B 392. Keeping the pressure constant, to double the volume of a given mass of an ideal gas at 27°C, the temperature should be raised to _____________ °C?
Correct answer: B
Explanation
Using Charles's Law (V1/T1 = V2/T2) with constant pressure, T2 must be double T1. Since T1 is 300 K (27°C), T2 is 600 K, which equals 327°C.
