A schematic of a horizontal cylindrical syringe submerged in a container of water labeled Constant-Temperature Water Bath. The syringe contains gas sealed by a plunger on the right. An arrow labeled slowly compressed points leftward against the plunger, reducing the volume of the gas inside.
A sealed syringe compressed isothermally in a water bath.
A sealed syringe containing an ideal gas at initial pressure \(P_0\) and initial volume \(V_0\) is placed in a constant-temperature water bath. The plunger is slowly pushed inward so that the gas is compressed isothermally to a final volume of \(\dfrac{1}{2}V_0\). Which of the following correctly predicts the final pressure \(P_f\) of the gas and provides a valid physical explanation based on kinetic theory?
