Question
A room temperature sample of xenon gas in a metal container with a piston has a volume of 1.00 L and a pressure of 4.0 atm. The piston is moved to change the volume of the container to 2.00 L, after which the pressure reads 1.75 atm. Which is the best explanation for this observation?
A.
The volume is miscalibrated and the actual final volume is 1.75 L.
B.✓ Correct
Some xenon has leaked out through the seal in the piston.
C.
The friction of moving the piston has caused the temperature of the gas to increase.
D.
The system is correctly calibrated, well sealed, and remains at room temperature.
