If you look at the experiment where you take a box of a given size, partitioned in the middle with two different gases, one in each compartment.
Pressure and temperature constant. As long as the two gases are kept separate the system is ordered.
however when you open the gate and the gases mix the system is disordered.The mass hasn't changed and neither has the pressure or temperature.
