Pf = P;/2 A sample of an ideal gas at P, is initially confined to one chamber of the apparatus represented above, and the other chamber is initially evacuated. The valve connecting the chambers is opened, and the gas expands at constant temperature to fill both chambers. Which of the following best describes AS for the process? A AS 0 because the gas particles become dispersed in a larger volume.

A sample of an ideal gas at P; is initially confined to one chamber of the apparatus represented above, and the other chamber is initially evacuated. The valve connecting the chambers is opened,
and the gas expands at constant temperature to fill both chambers. Which of the following best describes AS for the process?
A
AS <O because the pressure of the gas decreases by half.
AS = 0 because there is no change in the total number of particles of the gas.
AS = 0 because the average kinetic energy of the gas particles is unchanged.
AS > 0 because the gas particles become dispersed in a larger volume.
