1. The problem statement, all variables and given/known data when ethanol an dwater are mixed, is randomness increased or decreased 2. Relevant equations 3. The attempt at a solution Since these are miscible, I 'm equating that with 'comfortable' as a mixture and the 'comfort' being like a smaller amount of entropy than when the two are together but not mixed However, I'm uncertain about this conclusion that I've drawn as an answer. The fact that heat is released in the process suggests to me a minimum energy favours the mixed versus the solution of one in the other. Do these ideas sound reasonable?
