Problem

A rigid container of volume

2.0\,\text{m}^3

is divided into two equal compartments by an internal barrier. The left compartment contains

2.0\,\text{mol}

of an ideal monatomic gas, and the right contains

4.0\,\text{mol}

of the same gas. Both compartments are at

300\,\text{K}

. The barrier is removed without allowing any energy exchange with the surroundings, and the gases mix until uniform. What is the final pressure in the container? a)

4.7\,\text{kPa}

15\,\text{kPa}

7.5\,\text{kPa}

3.7\,\text{kPa}
