    When you make ice cubes, the entropy of water:

    A) does not change

    B) increases

    C) decreases

    D) may either increase or decrease depending on the process used

    Correct Answer: C

    Solution :

    The entropy function gives us a numerical measure of the irreversibility of a given process, i.e., it is a measure of disorder of a system. During formation of ice cubes orderedness increases, i.e., disordemess decreases, hence entropy decreases.
