a. Figure 1. The m ixing of two gases can be seen as two separate expansion. a) Expansion of gas 1 alone when the barrier is removed. The molecules have twice as many available microstates in the open box. b) Expansion of gas 2 alone.

a Figure 1. The mixing of two gases can be seen as two separate expansion. a) Expansion of gas 1 alone when the barrier is removed. The molecules have twice as many available microstates in the open box. b) Expansion of gas 2 alone. c) The simultaneous expansion of gases 1 and 2 is equivalent to mixing. b c
