Question

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.

Hint:

Remember that temperature in gas laws should be in Kelvin. To convert from Celsius, add 273 to the Celsius temperature.

Answer 1

According to Gay-Lussac’s Law, for a gas at constant volume, pressure is directly proportional to temperature in Kelvin:\[\frac{P_1}{T_1} = \frac{P_2}{T_2}\]Given an initial temperature of \( 27^\circ C = 300 K \), doubling the pressure requires a final temperature \( T_2 \) of \( 600 K \). This corresponds to \( 327^\circ C \).Therefore, the correct answer is \( 327^\circ C \).
