  1. Actually, according to the Second law, the warm soda heats the ice cube, right?

  2. well the second law states that natural processes go in a direction that maintains or increases the total entropy of the universe.
    entropy is the measure of disorder in a system, so I really do not know the best way to answer this problem

  3. Heat flows from warmer bodies to colder bodies. That is why the drink cools. The ice melts, and the drink loses heat in the process.

    Entropy decreses because the entropy loss of the liquid, dQ/T1, is less than the entropy gained by the ice, dQ/T2.
    The dQ's are the same ,but T1 > T2.
