Why doesn't oil and water mix?

  1. Sep 28, 2012 #1
    1. The problem statement, all variables and given/known data

    Explain why water and oil doesn't mix at room temperature using the entropy and free energy that you found to explain.

    2. Relevant equations

    The entropy that I found is -(Kb)ln(2) and the free energy is (Kb)(T)ln(2).

    3. The attempt at a solution

    Can someone direct me in the right path how to go about this question. I'm thinking it might be do to endothermic and exothermic reactions but I'm not sure.

    You found the entropy and free energy of what?

    I found it for water molecules around a hydrophobic molecule when multiplicity is reduced from 6 to 3
