| Oct 4, 2016 at 0:43 | comment | added | reductionista | Mixing entropy, also called entropy of mixing, is entropy due to different things getting mixed together. For example, when you add cream to a cup of coffee the cream starts out in a blob somewhat separate from the rest of the coffee. This has low entropy. But naturally and spontaneously, the cream will start to mix with the coffee spreading out and eventually the entire cup of liquid will be homogenous. This is because a mixed state always has higher entropy than a separated state. The highest entropy state is the one which has the maximum number of ways of rearranging the components. | |
| Oct 4, 2016 at 0:35 | comment | added | BLAZE | Thank you for your answer, I have never heard of "mixing entropy" before. Would you care to elaborate on it a bit please? Also as mentioned below the other answers; I won't be able to accept any answers just yet as I am awaiting an answer from Albert Aspect as promised in the comments below my question. So all I can give is (+1) for now. Best regards. | |
