Question
Please answer the following question:
When we considered the entropy of mixing, we found that the entropy change for material B was: Delta SB=-Nk(x/nx) ,where x=NB/N. Explain mathematically why Delta SB is definitely positive. Imagine that the mixing occurs as indicated by Fig. 2.15 (that is, by removing a partition separating materials A and B). Explain PHYSICALLY why Delta SB is definitely positive. Imagine that the mixing occurs by forcing particles of A into a fixed volume containing B, Explain PHYSICALLY why Delta SB is definitely positive. Figure 2.15. Two different gases, separated by a partition. When the partita is removed, each gas expands to fill the whole container, mixing with the other and creating entropy.
