In experiment $A$, a student mixes ink with water and notices that the two liquids mix evenly. In experiment $\mathrm{B}$, the student mixes oil with water; in this case, the liquids separate into two different layers. The entropy change is: a. positive in experiment A and negative in experiment B. b. positive in experiment $\mathrm{A}$ and zero in experiment $\mathrm{B}$. c. negative in experiment $A$ and positive in experiment $B$. d. zero in experiment $A$ and negative in experiment $B$.
