How will the volume of a fixed sample of gas change if the pressure is doubled and its Celsius temperature is halved?

Question

Quizplus · Accepted Answer

The relationship between pressure, volume, and temperature of a gas is given by the combined gas law, which is $P_1V_1/T_1 = P_2V_2/T_2$, where $P$ is pressure, $V$ is volume, and $T$ is temperature in Kelvin. The question does not specify the initial and final temperatures in Kelvin, which are necessary to determine the exact change in volume. Since the Celsius temperature is halved, without knowing the initial temperature in Celsius, we cannot convert it to Kelvin and thus cannot determine the exact change in volume.
