A container of fixed volume contains a gas at 27°C. To double the pressure of the gas, the temperature of the gas should be raised to …. C.
Show Hint
Remember that temperature in gas laws should be in Kelvin. To convert from Celsius, add 273 to the Celsius temperature.

Solution and Explanation
For a gas in a fixed volume, the pressure is directly proportional to the temperature (in Kelvin) according to Gay-Lussac’s Law:
\[
\frac{P_1}{T_1} = \frac{P_2}{T_2}
\]
Let the initial temperature be \( 27^\circ C = 300 K \). To double the pressure, the final temperature \( T_2 \) should be \( 600 K \), which is equivalent to \( 327^\circ C \).
Thus, the correct answer is \( 327^\circ C \).
